Question

Please help ASAP starting to fall behind! This equation really confuses me and if someone could help that would be amazing!

Given the function:

f(x) = x² - 4x - 2

Find the following values.
a) f(2)
f(2)=

b) f(4)
f(4)=

c) f(-3)
f(-3)=

Answer 1

f(2) = 2^2 - 4*2 - 2 = 4 - 8 - 2 = -6

f(4) = 4^2 - 4*4 - 2 = 16 - 16 - 2 = -2

f(-3) = (-3)^2 - 4*-3 - 2 = 9 + 12 - 2 = 19
