Question

Consider the function f(x) = x2 + 3x − 7. Find the value of f(x) when x = 3 and select the correct answer below.

Answer 1

fxx=x2+3x−7xf=x2+3x−7xAnswer:f=x2+3x−7x

Answer 2

f(x) = x2 + 3x − 7.
f(x) = 6 + 9 -7
f(x) = 9
*3 times 2 = 6
*3 times 3 = 9
so thats where the 6 and 9 came from
6 + 9 = 15
15 - 7 = 8
so f(x) =8
