If I remember correctly this is how you solve it.

f(x)=8x+6
f(-1)=8(-1)+6
f(-1)=-8+6
f(-1)= -2

F(x) = 8x + 6

To find f(-1), substitute x = -1 :

f(-1) = 8(-1) + 6 = -8 + 6 = -2

Answer: f(-1) = -2

I'm guessing you want the volume?

so for a triangle it's 1/2 base * height for the area

1/2 * 8 * 3 = 12

12*20=240 m^3

Enter the domain and range of the function g(x) = 9x2 − 5 as an inequality, using set notation and using interval notation. Comp

tia_tia [17]

The domain and the range of a function are the set of input and output values, the function can take.

The domain and the range of $g(x) = 9x^2 - 2$ is $(-\infty, \infty)$ .
The parent function $f(x) =x^2$ is vertically compressed by 9, then shifted down by 5 units to get $g(x) = 9x^2 - 2$

Given

$g(x) = 9x^2 - 2$

Domain and range

There is no restriction as to the input and the output of function g(x).

This means that the domain and the range are $(-\infty, \infty)$

$(-\infty, \infty)$ is in interval notation

The corresponding set notation is: $- \infty < x < \infty$

The parent function

We have:

$f(x) = x^2$

First, the parent function is vertically compressed by a factor of 9.

The rule of this transformation is:

$(x,y) \to (x,9y)$

So, we have:

$f'(x) = 9x^2$

Next, the function is shifted down by 5 units.

So, we have:

$g(x) = f'(x) - 5$

$g(x) = 9x^2 - 5$
