consider the quadratic function f(x) = x^2 - 8x - 4. what is the value of the leading coefficient? -8 -4 0 1

Explanation:

Step1: Recall quadratic function form

The general form of a quadratic function is $f(x)=ax^{2}+bx + c$, where $a$ is the leading - coefficient.

Step2: Identify coefficients in given function

For the function $f(x)=x^{2}-8x - 4$, comparing it with $ax^{2}+bx + c$, we have $a = 1$, $b=-8$, and $c=-4$.

Answer:

D. 1
