Which of the following shows the graph of y=2e^x?

The third one.

Step-by-step explanation:

When x=0, the function y=2e^x equals:

y=2e^x = 2e^(0) = 2.

For that reason, the graph should cross the y-axis at the point (0, 2). The only graph that meets this requirement is the third one :).

For this case we must indicate the graph corresponding to the following equation:

Then, we evaluate the equation for

We have by definition, any number raised to zero results in 1.

So:

Now we evaluate the equation for x = -1

We already have two points to graph:

Observing the options, we realize that the correct option is option C.

It should be noted that graphs A and D, by definition, do not correspond to the exponential function.

Option C

(0,,,0)

step-by-step explanation:

the table of x and y values is shown in the attached pic(part of question)

we have to decide according that graph

given points are (0, 0) (–1, 0), (2, 0)

when we graph these points on graph they show an increasing line as shown in the attached pic

x is the total time in minutes for the free response

you are given number of questions as 15 - m and time per item as 8 minutes

to find x multiply the two givens together:

x = 8 * (15-m) = 8(15-m)
