Question

graph this function: $f(x) = x^2 - 4x - 5$
step 1: identify $a$ and $b$.
$a = \underline{\quad}$, $b = \underline{\quad}$

Explanation:

Step1: Recall quadratic form

The quadratic function is in the form \( f(x) = ax^2 + bx + c \).

Step2: Identify coefficients

For \( f(x) = x^2 - 4x - 5 \), compare with \( ax^2 + bx + c \). So \( a = 1 \), \( b = -4 \).

Answer:

\( a = 1 \), \( b = -4 \)
