Which of the following shows the graph of y=2e^x
MatroZZZ [7]
<h2>Hello!</h2>

The answer is:

The first option shows the graph of the given function.

<h2>Why?</h2>

Since the given function is an exponential function, we are looking for an exponential function graph, with a function that intercepts the y-axis at y equal to 2, or the point (0,2).

So, since we are given just one exponential graph, let's find the y-axis intercept in order to assure that the correct option is the first graph.

The function is:

y=2e^{x}

Finding the y-axis intercept, we need to make "x" equal to 0, so:

y=2e^{0}

We need to remember that any number elevated or powered to 0 is equal to 1, so:

y=2*1=2

We have that the function intercepts the y-axis at y equal to 2, or the point (0,2).

Finding the x-axis intercept, we need to make "y" equal to 0, so:

y=2e^{x}

0=2e^{x}

Ln(0)=Ln(2e^{x})

Now, since the natural logarithm of "0" does not exist in the real numbers, we can see that there is not x-axis intercept for this function.

Hence, the first option shows the graph of the given function.

Have a nice day!

Note: I have attached a picture for better understanding.

What is the surface area of a square pyramid with a base of 12cm and a slanted height of 8cm?
Anastaziya [24]
Base:
12*12= 144 cm^2

Triangle sides:
12*8/2= 48 cm^2 each

Multiply by 4 because there are four of them
48*4= 192 cm^2

Add the base
192+144=336 cm^2

Final answer: 336 cm^2
