Which exponential function has a growth factor of ?
a. f(x) = 2(0.5x)
b. graph
c. f(x) = 0.5(2x)
d. chart

So, only option-c and option-d are same

Step-by-step explanation:

(a) From Graph:

Firstly, we will find function of the graph

Let's assume exponential function as

we can select any two points and find 'a' and 'b'

At x=0 , y=1/2:

we can plug values

now, we can plug it back

and we get

At x=-1 , y=2:

we can plug values

now, we can plug it back

and we get

(b) From chart:

Firstly, we will find function of the graph

Let's assume exponential function as

and we get

At x=1 , y=1:

we can plug values

now, we can plug it back

and we get

The answer is A

its 69.420

step-by-step explanation:

the final price would be 29.6925

step-by-step explanation:

39.59 minus 25% equals 29.6925
