angelab97 · Answer

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

angelab97 · Answer

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

nory · Answer

Oh, thanks.

nory · Answer

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?)

angelab97 · Answer

how did you get -4?

nory · Answer

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