suter [353]3 years ago

Answer:

B) 19

Step-by-step explanation:

The first step is to substitute 2 for x into the equation. f(2) = 2(3^2)+1

The second step is to square 3 which equals 9. f(2) = 2(9)+1

The third step is to multiply 2 by 9 which equals 18. f(2) = 18+1

The fourth step is to add 18+1 which equals 19. f(2) = 19

What are the intercepts of f(x)=5x-45
Mnenie [13.5K]
The y-intercept of f(x) = 5x - 45 would be -45, as that is what is represented in the equation. The way to find the x-intercept would be to solve the equation when f(x) = 0.

     0 = 5x - 45
+ 45         + 45

   45 = 5x
    /5     /5
     9 = x

And there we have it.
The intercepts of f(x) = 5x - 45 are as follows:

y-intercept = -45
x-intercept = 9
