Question

F(x)=x2–5x+7, find f(3)

Answer 1

Answer:

$f(3) = 1$

Step-by-step explanation:

f(x) = x² - 5x + 7

To find f(3) substitute the value of x that's 3 into f(x) that's replace every x in f (x) by 3

We have

$f(3) = {3}^{2} - 5(3) + 7 \\ = 9 - 15 + 7 \\ = - 6 + 7$

We have the final answer as

$f(3) = 1$
