Chapter 3.3, Problem 83AYU

To determine

To calculate: Quadratic function.

Answer to Problem 83AYU

The quadratic function is $f\left(x\right)=2\left(x+4\right)\left(x-2\right)$ .

Explanation of Solution

Given information:

  $x$ intercepts are $-4,2$

Range is $[-18,\infty )$

Concept Used:

Quadratic Function:

  $F\left(x\right)=a{x}^2+bx+c$

Where, $a,b,c$ are constants.

Calculation:

  $f\left(x\right)=2\left(x+4\right)\left(x-2\right)$ has $x$ intercepts $-4,2$ and range is $[-18,\infty )$
