Which of the following shows the graphic representation of the exponential function f(x) = 3*?

answer:

Step-by-step explanation:Option B is correct.

Step-by-step explanation:

The exponential function is in the form of :

where, a is the initial value and b is the growth rate.

If b > 1 , then the graph is exponentially growth.

If 0< b< 1, then the graph is exponentially decay.

Given the exponential function:

on comparing with [1] we have;

a =1 and b = 3 > 1

⇒ the function is exponentially growth.

y-intercept:

Substitute x = 0 and solve for y:

then;

y-intercept = (0, 1)

or

Initial value = 1

End behavior:

If , then

and

If , then

Therefore, the option B is correct.

$25

step-by-step explanation:

25 - 4.50 = 20.5

20.5 / 2 = 10.25

10.25 + 10 = 20.25

20.25 - 12.50 = 7.75

therefore the answer is $25 as shown as the first number.
