Answer:

Step-by-step explanation:

It is two types of function.
- Exponential Growth: If function increase as value of x increase.
In this case, a>0 and b>1
- Exponential decay: If function decrease as value of x increase.
In this case, a>0 and 0<b<1
We need to choose exponential growth function.

Here a=0.75>0 and b=5>1
Therefore, This function is exponential growth.
Answer:
y = 1/2x - 7
Step-by-step explanation:
y = 1/2x + b
-4 = 1/2(6) + b
-4 = 3 + b
-7 = b
Answer:
The zeros are:

- The function has three distinct real zeros.
Hence, option (B) is true.
Step-by-step explanation:
Given the expression

Let us determine the zeros of the function by putting h(x) = 0 and solving the expression

switch sides

as

so

Using the zero factor principle
so


Thus, the zeros are:

It is clear that there are three zeros and all the zeros are distinct real numbers.
Therefore,
- The function has three distinct real zeros.
Hence, option (B) is true.
If the law is basically if unemployment goes up 1% then the GDP goes down 2%, then the unemployment rate going down 3% means the GDP will go up 6%
