1. The table shows values of a function f (x). What is the average rate of change of f (x) over the interval from x = 5 to x = 9? Show your work.

x | 4 | 5 | 6 | 7 | 8 | 9 | 10 |
f(x) | -4 | -2 | 8 | 10 | 11 | 14 | 18 |


2. Given $f(x)=4x^2 +6x$ and $g(x)=2x^2 + 13x + 15$, find $(\frac{f}{g})(x).$ Show your work.


3. Given$f(x)=x^2 - 6x + 8$ and $g(x)=x-2$, solve $f(x)=g(x)$ using a table of values. Show your work.


Much thanks and appreciation!

Answer 1

Answer:

y=0.9x-45

Step-by-step explanation:

When you substitute the values of x you have to get same values as given in the table

For example: substitute x=50 in the equation y=0.9x-45

Y= 0.9(50)-45

Y= 45-45

Y=0
