Answer:
Not an exponential function. The exponent is a constant.
Step-by-step explanation:
An exponential function has the variable in the exponent. This function raises the variable to a fixed power, so it is not an exponential function.
The answer is $83
65+9+9=83
Or
9x2=18
18+65=83

If b was equal to zero, then x would be undefined.
Also note:
As the value of b increases, the value of x decreases. And vice versa.
Answer:
7x+12
Step-by-step explanation:
You do 10x-3x since they both have the x variable they can be combined to make 7x and the 12 is left alone.
