Consider the quadratic function f(x) = –2x2 5x – 4. the leading coefficient of the function is?
evablogger [386]

Answer:

\text{-2 is the leading coefficient of the quadratic equation }f(x)=-2x^2+5x-4

Step-by-step explanation:

Given the quadratic function

f(x)=-2x^2+5x-4

we have to find the leading coefficient of given quadratic equation.

\text{The general form of quadratic equation is }ax^2+bx+c=0

The coefficient of x^2 i.e a is known as the leading coefficient.

Comparing given equation with the standard equation, we get

a=-2

\text{Hence, -2 is the leading coefficient of the quadratic equation }f(x)=-2x^2+5x-4
