a quadratic function $f(x)$ is hidden from view. you must find the $y$-intercept(s) of $f(x)$ and write the answer(s) in the form $(x, y)$. choose the form of the quadratic function $f(x)$ that you would like to see in order to answer the question most efficiently.
form: standard form
$f(x) = -3x^2 + 18x - 24$
answer attempt 1 out of 2
there are no y-intercepts

Explanation:

Step1: Recall y-intercept definition

The y-intercept occurs at $x=0$, so substitute $x=0$ into $f(x)$.

Step2: Calculate $f(0)$

$$\begin{align*} f(0) &= -3(0)^2 + 18(0) - 24\\ &= 0 + 0 - 24\\ &= -24 \end{align*}$$

Answer:

$(0, -24)$
