Question

Use the given function to complete parts​ (a) through​ (e) below.
f left parenthesis x right parenthesis equals x Superscript 4 Baseline minus 9 x squared
Find the​ y-intercept by computing​ f(0).

Answer 1

To find the \( y \)-intercept of the function \( f(x) = x^4 - 9x^2 \), you'll need to evaluate the function at \( x = 0 \).

Calculate \( f(0) \):

\[
f(0) = 0^4 - 9(0^2)
\]

\[
f(0) = 0 - 0 = 0
\]

Thus, the \( y \)-intercept is \( (0, 0) \).
