Question

Pleasee help
f(x) = 3x² - 7x + 4
f(2)= [?]

Answer 1

f(2) = 2

Explanation:

We are given
f(x) = x² - 7x + 4

To find f(2), just plug in 2 wherever you see an x and simplify

f(2) = 3 · 2² - 7 · 2 + 4

= 3 · 4 - 7 · 2 + 4

= 12 - 14 + 4

= 2

Answer 2

f(2) = 3*2^2 - 7*2 + 4
f(2) = 12 - 14 + 4 = 2
