Question

Consider the function f(x) = x2 − 2x + 6. Find the value of f(x) when x = 3 and select the correct answer below.

a) 1
b) 3
c) 6
d)9

Answer 1

is the first 2 of the x an exponent???

Answer 2

So we know that \(f(\color{red}{\textbf x}) = \color{red}{\textbf x}^2-2\color{red}{\textbf x}+6\)

So we have \(f(\color{red}{\textbf 3}) = \color{red}{\textbf 3}^2-2(\color{red}{\textbf 3})+6=\cdots~?\)

Answer 3

yes sorry, and f(3) = 9?

Answer 4

That's right.

Answer 5

thank you :)
