What is the exponential function in figure ?

D

Step-by-step explanation:

I see the curve given crosses the point (1,3).

So let's check and see which of the given equations is satisfied by that point.

Checking choice A:

with (x,y)=(1,3):

So choice A is not right.

Checking choice B:

with (x,y)=(1,3):

So choice B is not right.

Checking choice C:

with (x,y)=(1,3):

So choice C is not right.

Checking choice D:

with (x,y)=(1,3):

So choice D is the only choice that would contain the point (1,3) when graphed.

So choice C is not right.

D

Step-by-step explanation:

The standard form of an exponential function is

y = a

Using points from the graph to find a and b

Using (0, 6 ), then

6 = a = a × 1 ⇒ a = 6

Using (1, 3 ), then

3 = 6 ⇒ b = =

The exponential function is

f(x) = 6 → D

pay attention in your classes and concentrate the best thing you can do to raise your test scores is to pay attention when you're supposed to be learning the material: in class!

take good notes.

do your homework.

use mnemonics and other tricks.

do practice tests.

note: the best i know.
