Question

1. Given f(x) = x2 - 4x + 5, find each value.
a. f(2)

Answer 1

Knowing
`f(x)=x^2-4x+5` then
`f(2)=2^2-4\cdot2+5=4-8+5=1`

Hope this helps :)

Answer 2

1

Explanation:

f(x) = x^2 - 4x + 5

Plug in:

f(x) = x^2 - 4x + 5

f(x) = 2^2 - 4(2) + 5

f(x) = 4 - 8 + 5

f(x) = -4 + 5

f(x) = 1

Hope this helped.
