First, multiply the first equation by 3 to get:

3x+3y=-6

Then, add the two equations together to get

8x=16

We can follow that x=2. Plugging in x=2, we get that y=-4.

Therefore, the solution of (2,-4)

Use the graph of the function y = 4x to answer the following questions.
Sav [38]

Hello from MrBillDoesMath!

Answer:

For y = 4x, the domain of the function is all real numbers. This can be indicated  as ( -infinity, infinity),

...later part of question:...

..."because an exponent can be any real"

exponent?   !!!

Did you mean y = 4^x ? In this case the domain of y is all real numbers ann the range is (0, infinity), where the value 0 is not included in the range.

Thank you,

MrB
