Just give me a sec to type it out, it's a graph thing.
OpenStudy (danjs):

The following table shows the values of f(x) and g(x) for different values of x:
x 1 2 3 4 5
f(x) 4 16 64 256 1,024
g(x) -1 -1 -1 -1 -1
OpenStudy (anonymous):
Which of the following best describes the function f(x) + g(x)?
4x - 1x
-1(4x)
4x - 1
4x - 1

ok
OpenStudy (anonymous):
?
OpenStudy (danjs):
g(x) is a horizontal line, the value y=g(x) = -1 for any x value
OpenStudy (anonymous):
So which would it be?
OpenStudy (danjs):
are the 3rd and 4th answers the same?

No. The third is 4 to the power of x -1 and the fourth is 4 to the x power - 1
OpenStudy (danjs):
oh
OpenStudy (danjs):
the answer will be in the form f(x) - 1
let me see if f(x) is linear or exponential
OpenStudy (anonymous):
ok
OpenStudy (danjs):
yeah from the table, f(x) = 4^x

so f(x) + g(x) = 4^(x) - 1
OpenStudy (danjs):
\[4^{x} -1\]
OpenStudy (anonymous):
Okay!
