Find the equation of the graph in function notation. name your function "f" and use x as your variable.

Step-by-step explanation:

The equation of the graph can be obtained using the formula:

From the graph, the y-intercept is -1 and the x-intercept is 2

We substitute these values to get:

This implies that;

Or

The function notation is

hello from mrbilldoesmath!

answer:

25x^2 + 90x + 84

discussion:

mn(x) = m(n(x)) = m( 5x + 9) =

(5x + 9)^2 + 3 =>

25x^2 + 90x + 9^2 + 3 =

25x^2 + 90x + 84                 (as 9^2 = 9*9 = 81)

which is the second choice
