The illustration below shows the graph of y as a function of x. This is the graph of a (linear/nonlinear) function.
The y-intercept of the graph is the function value y=___.
The smallest positive x-intercept of the graph is located at x=___.
The greatest value of y is y=___.
For x between x= -pi and x=-pi/2 , the function value y (greater than, less than, equal to) 0.

c.

step-by-step explanation:

because first you have to add the 4x, 9x, and the 7x together and you get 20x and then you add the last numbers up and you get 5and then you put the subtraction sign in there and that's how you get the answer.

b) k’(6, 4); l’(3, 3)

step-by-step explanation:

a 270° clockwise rotation maps every point (x, y) to (y, -x). (it negates the x-coordinate and then switches it and the y-coordinate.)

this means the endpoints of the side congruent to kl, k' and l', would be mapped as:

k'(-4, 6)→(6, 4)

l'(-3, 3)→(3, 3)

the answer is b
