Answer:
h=3y+9
Step-by-step explanation:
We will write an expression using the y=mx+b format.
h in this case will be the height at any given year.
3 is the rate at which the three grows, y will represent any given year.
9 is the starting rate, or your y intercept.
|x| is greater then 5 on |X|>5 and the other x is lees then 5 on |X|<5
Given:
The function is:
To find:
The inverse of the given function, then draw the graphs of function and its inverse.
Solution:
We have,
Step 1: Substitute .
Step 2: Interchange x and y.
Step 3: Isolate variable y.
Step 4: Substitute .
Therefore, the inverse of the given function is and the graphs of these functions are shown below.
Since D>0 , the quadratic equation has 2 real solutions
