Answer:
[tex]f(3) = 1[/tex]
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
[tex]f(3) = {3}^{2} - 5(3) + 7 \\ = 9 - 15 + 7 \\ = - 6 + 7[/tex]
We have the final answer as
[tex]f(3) = 1[/tex]
Hope this helps you
