Chapter 8.7, Problem 17WE

(a)

To determine

To find: The value of the given function.

Answer to Problem 17WE

The value of the given function is $46$ .

Explanation of Solution

Given:

The given function is $h\left(a\right)=3{\left(a\right)}^2-2$ .

The given set of real number is $h\left(4\right)$ .

Calculation:

Consider the given function is,

  $h\left(a\right)=3{\left(a\right)}^2-2$

Consider the real number $h\left(4\right)$ .

Then,

  $\begin{array}{c}h\left(4\right)=3{\left(4\right)}^2-2\\ =46\end{array}$

(b)

To determine

To find: The value of the given function.

Answer to Problem 17WE

The value of the given function is $48$ .

Explanation of Solution

Given:

The given function is $h\left(a\right)=3{\left(a\right)}^2-2$ .

The given set of real number is $h\left(-5\right)$ .

Calculation:

Consider the given function is,

  $h\left(a\right)=3{\left(a\right)}^2-2$

Consider the real number $h\left(-5\right)$ .

Then,

  $\begin{array}{c}h\left(-5\right)=3{\left(-5\right)}^2-2\\ =48\end{array}$

(c)

To determine

To find: The value of the given function.

Answer to Problem 17WE

The value of the given function is $-2$ .

Explanation of Solution

Given:

The given function is $h\left(a\right)=3{\left(a\right)}^2-2$ .

The given set of real number is $h\left(0\right)$ .

Calculation:

Consider the given function is,

  $h\left(a\right)=3{\left(a\right)}^2-2$

Consider the real number $h\left(0\right)$ .

Then,

  $\begin{array}{c}h\left(0\right)=3{\left(0\right)}^2-2\\ =-2\end{array}$
