Question

The function is graphed in the above. If the function is defined by , for how many values of between and does equal ?

Answer 1

You might be missing some numbers here...

Answer 2

g(x)= f(x) +4 for how many values of between -5 and 15 does g(x)=0?

Answer 3

the function is defined by g(x)= f(x) +4

Answer 4

Oh, thanks.

Answer 5

So g(x) is always four greater than f(x).
Now, we are looking for values where g(x) = 0 (between 15 and -5). Such places must have f(x) = -4. (Does that make sense?)

Answer 6

how did you get -4?

Answer 7

I did something to both sides of the equation:
g(x) = f(x) + 4
-4 - 4
g(x) - 4 = f(x)
