Step-by-step explanation:

Exponential function $y=a\cdot b^x$ represents

exponential growth if b1;

exponential decay if

Consider all options:

A. In the exponential function y=(0.25)^x,

b=0.25

so it represents exponential decay.

B. In the exponential function y=7^x,

b=71,

so it represents exponential growth.

C. In the exponential function $y=\dfrac{1}{3}(0.1)^x,$

b=0.1

so it represents exponential decay.

D. In the exponential function $y=\left(\dfrac{2}{3}\right)^x,$

$b=\dfrac{2}{3}$

so it represents exponential decay.

the coldest point would be 4 degrees.

Step-by-step explanation:

On a nuber line you would plot the point 13 and go back on the number line 9 units and you would get 4 degrees.
