Understanding exponential and logarithmic functions

Does this function represent growth or decay?
y=10(.3)^x

• Growth
• Decay

Power Function or Not?

 $y=\frac{1}{1+x^2}$  

• yes

• no

Is this function, exponential growth or decay?

(1/2^x)

• Exponential growth

• Exponential decay

What is the initial value $\left(a\right)$ in the table given?

• $64$

• $32$

• $16$

• $8$

Which of the following is the correct exponential form for:

6 x 6 x 6

• 6³

• 3⁶

• -6³

• (-6)³

• the first term

• the multiplier

• the divider

• the zero term or y-intercept

Answer explanation

If you substitute n=0 into the equation, it should also equal 65.

 $y=\frac{1}{3}^x$  

• Growth

• Decay

• Neither
