Can someone me asap you know i you when needed anyways i need to be able to plot the x and y coordinates so how do i do that? when y=5 times 2^x x is the value i need to plug in to plot it on the graph the graph goes up until 20 so i just need some x values

The equation y=5(2^x) gives you everything you need to plot any number of points.  You can give x any value and then just solve for y.  So what you are doing is giving the x coordinate and solving the equation for the y coordinate.  I like to keep it simple.  Try using 0, 1, -1, 2, and -2 for the x coordinates.

y = 5(2^x)
y = 5(2^0)
y = 5(1)
y = 5

So when x is 0, y is 5  (0, 5)

y = 5(2^1)
y = 5(2)
y = 10

So when x is 1, y is 10  (1, 10)

y = 5(2^-1)
y = 5(1/2)
y = 5/2

So when x is -1, y is -10   (-1, 5/2)

y = 5(2^2)
y = 5(4)
y = 20

So when x is 2, y is 20    (2, 20)

y = 5(2^-2)
y = 5(1/4)
y = 5/4

So when x is -2, y is 5/4    (-2, 5/4)

Now plot the points and it should look something like this... (see the pic)
