You said this was an "exponential function".....is THIS what you mean?

y = 4x

If so, substitute a domain element for "x", and evaluate.

For example, if your function was y = 2x and your domain was [0, 3, 5], you might pick the domain element 3. Substitute that for x:

y = 23
Then do the arithmetic. 23 means 2*2*2, or 8.

So, when x = 3, y = 8.

If I have interpreted your function correctly, do the same sort of thing with it.

3. ## no understand

im not understanding functions tht well i was given a math assignment and was told to finish it and it was so hard i couldnt do it fyi im in 6th grade
