Question

The function f(x)
can be described by the equation f(x)=x2−5
.(1 point)
Find the value of f(4)=

Answer 1

To find the value of \( f(4) \) for the function \( f(x) = x^2 - 5 \), you can substitute \( x \) with \( 4 \):

\[
f(4) = 4^2 - 5
\]

Calculating \( 4^2 \):

\[
4^2 = 16
\]

Now subtract \( 5 \):

\[
f(4) = 16 - 5 = 11
\]

Thus, the value of \( f(4) \) is \( 11 \).
