Answer:

f(x) is linear

g(x) is exponential

Step-by-step explanation:

A linear function will always have the same rate of change between equally distant points, while an exponential function will have an increasingly large rate of change between equally distant points.

First, look at f(x). All these points are equally distant at 2 units apart on the x-axis, so they can be directly compared:

(-38)-(-18)=-20\\(-58)-(-38)=-20\\(-78)-(-58)=-20

All of these points are the same distance apart on the y, so f(x) must be a linear function.

Now look at g(x). These are also all equally distant at only 1 unit apart.

30-10=20\\90-30=60\\270-90=180

These are very clearly not the same distance apart on the y, so g(x) must be the exponential function.

rugs Emporium installs carpet for $80 plus $9.50 per square yard of carpet carpets 4 U charges $120 for installation and $7.50 p
mihalych1998 [28]

The area of the carpet must be <u>greater than 20 square yards</u> for which Rugs Emporium charges more than Carpets 4U.

<u><em>Explanation</em></u>

Suppose, the number of square yards of carpet is  x

Rugs Emporium charges $80 plus $9.50 per square yard of carpet. So, the total charge for x square yards of carpet = (80+9.50x) dollar

Carpets 4U charges $120 for installation and $7.50 per square yard of carpet. So the total charge for x square yards of carpet =(120+7.50x) dollar

If the Rugs Emporium charges more than Carpets 4U , then the inequality will be.....

80+9.50x>120+7.50x\\ \\ 9.50x-7.50x>120-80 \\ \\ 2x>40\\ \\ x>20

So, the area of the carpet must be greater than 20 square yards for which Rugs Emporium charges more than Carpets 4U.
