Question

Consider the function f(x) = 8 − 3x2. Find the value of f(x) when x = 3 and select the correct answer below.
A.) −19
B.) −10
C.) 26
D.) 35

Answer 1

Replace x with 3, then evaluate to get
\[\Large f(x) = 8 - 3x^2\]
\[\Large f(x) = 8 - 3(x)^2\]
\[\Large f({\color{red}{x}}) = 8 - 3({\color{red}{x}})^2\]
\[\Large f({\color{red}{3}}) = 8 - 3({\color{red}{3}})^2\]
\[\Large f(3) = ???\]
