Answer:
Answer to5)y=3
Answer to q9)x=3
5. y = 3.
6. y = (2/3)x.
7. y = x - 1.
8. y = x + 3.
9. x = 3.
10. y = - 3x.
What is a graph?The set of ordered pairings (x, y) where f(x) = y makes up the graph of a function.
These pairs are Cartesian coordinates of points in two-dimensional space and so constitute a subset of this plane in the general case when f(x) are real values.
5. The graph of this function is constant for all values of x, y = 3.
6. The graph of this function has points (0, 3) and (3, 2).
m = (2 - 0)/(3 - 0).
m = 2/3.
2 = (2/3)×3 + b.
2 = 2 + b.
b = 0.
y = (2/3)x.
7. The graph of this function has points (0, 1) and (3, 2).
m = (2 - 0)/(3 - 1).
m = 2/2.
m = 1.
2 = 1(3) + b.
2 = 3 + b.
b = -1.
y = x - 1.
8. The graph of this function has points (- 3, 0) and (0, 3).
m = (3 - 0)/(0 + 3).
m = 1.
3 = 1(0) + b.
b = 3.
y = x + 3.
9. The graph of this function is a vertical line parallel to the y-axis,
x = 3.
10. The graph of this function has points (0, 0) and (- 1, 3).
m = (3 - 0)/(- 1 - 0).
m = 3/ - 1.
m = - 3.
0 = - 3(0) + b.
b = 0.
y = - 3x.

The second option
Explanation
Couterclockwise is rotating to the left, so if you rotate the green thing to the left it would be the same as the second option
Answer:
The second option to the right on top.
Step-by-step explanation:

What is the method of determination of power of prime in Factorial ?Let p is the prime number whose power is to be found
Let n is the factorial number then
p in n! = (n /p) + (n/p²) +(n/p³) + .......
until Numerator < Denominator
and after division only the integer part is taken
Therefore to determine the power of 2 in 400!
2 in 400! = (400 /2) + ( 400 /2²) + (400 /2³) +(400 /2⁴) +(400 /2⁵) +(400 /2⁶) +(400 /2⁷) +(400 /2⁸) + above this N < D
2 in 400! = 200 +100 +50+25+12+6+3+1
2 in 400 = 397
Therefore the power of 2 in 400! is 397.

On what interval(s) of x is f(x) positive?
On what interval(s) of x is f(x) negative?
Answers
Answer:
Positive: (-2,1)
Negative: (-∞,-2) U (1,∞)
Step-by-step explanation:
The graph of the function f(x) is given in the figure. We can see some points like (-2,0), (-1,1), (2,-2), and many others.
Note the second value of each point (the value of y) is positive or negative. When it's positive, the graph is above the x-axis, when it's negative, the graph is below the x-axis. When it's 0, the graph crosses the x-axis.
To find the intervals of x where the function is positive, we only have to look into the zone where the graph is above the x-axis. It can be identified as the interval (-2,1).
Similarly, the function is negative in the interval (-∞,-2) U (1,∞)
The function f(x) is positive in the interval [-2, 1].
The function f(x) is negative the interval (-∞, -2) U (1, ∞).
The positive regions of a function f(x) are those intervals where the function is above the x-axis. It is where the y-values are positive (not zero).
To find the intervals of x where the function is positive,
In the interval [-2, 1] , the function f(x) is positive.
The negative regions of a function f(x) are those intervals where the function is below the x-axis. It is where the y-values are negative (not zero).
In the interval (-∞,-2) U (1,∞) , the function f(x) is negative.
y-values that are on the x-axis are neither positive nor negative. The x-axis is where y = 0.
when y = 0, x = -2, 1
Therefore, the function f(x) is positive in the interval [-2, 1] and negative in the interval (-∞,-2) U (1,∞).

Answer:
y = 4x +3
Step-by-step explanation:
The slope formula can be used to find the slope:
m = (y2 -y1)/(x2 -x1)
Using the first two lines of the table, we find the slope to be ...
m = (11 -7)/(2 -1) = 4/1 = 4
__
The y-intercept can be found from the relation ...
b = y -mx
Using the slope we found, and the first line of the table, we find the intercept to be ...
b = 7 -4(1) = 3
__
Then the equation is ...
y = mx +b . . . . . . slope-intercept form of the equation for a line
y = 4x +3
