Answer and Step-by-step explanation:

Are you interested in finding the solutions of f(x) = x² - 10x - 17, when x = 5 or x = 0? Let's try both!

Function Details

f(x) = x² - 10x - 17 x = 5

f(5) = 5² - 10(5) - 17

f(5) = 25 - 50 - 17

f(5) = -42

We repeat the procedure for the next function, only this time x = 0.

f(0) = 0² - 10(0) - 17

f(0) = 0 + 0 - 17

f(0) = -17

Answers: f(5) = -42 and f(0) = -17.

Answer 2

f(5) = - 42 , f(0) = - 17

Explanation:

(a)

to find f(5) substitute x = 5 into f(x)

f(5) = 5² - 10(5) - 17 = 25 - 50 - 17 = - 25 - 17 = - 42

(b)

to find f(0) substitute x = 0 into f(x)

f(0) = 0² - 10(0) - 17 = 0 - 0 - 17 = - 17
