Answer:

There is an infinite number of solutions.

Step-by-step explanation:

When you simplify the left side of the equation, you get -7n - 14, which is equal to the right side. If you were to plug in any number for n, it will equal the same on both sides of the equation.

Which point is one the graph of f(x) = 2 * 5^x?

marusya05 [52]

Answer:

(0,2)

Step-by-step explanation:

I'm going to assume you meant Which point is ON the graph of f(x) = 2 * 5^x?

In order to do this question, all you need to do is pick any number as x. Lets pick 0 in this case.

f(x) = 2 * 5^x

f(0) = 2*5^0

= 2*1

= 2

So one point on the graph would be (0,2)

Why?

Because remember with functions, the f(x) can be swapped out with y, so when x = 0, y = 2.
