SOLUTION: please help me solve g(-10) if g(x)=70

Question 72617: please help me solve g(-10)
if
g(x)=70
Answer by bucky(2189) (Show Source): You can put this solution on YOUR website!
You are given that:
.
g(x) = 70
.
Then to find g(-10), all you need to do is to go to the equation for g(x) and substitute -10
for every x you find and simplify the result.
.
In this problem you would get:
.
g(-10) = 70
.
Because there are no terms on the right side that contain an "x" there is no place that you
put a -10 on the right side. The right side just remains "70" and there is no need for
further simplifying. So the answer to your question is just:
.
g(-10) = 70
.
If your original problem had really been:
.

.
and you were then asked to find g(-10) you would go about it in the same way. That is
you would go to g(x) and replace every x with -10 to get:
.

.
Then you would simplify the right side knowing that and .
Substituting these values you would get:
.

.
So for the new problem g(-10) would be 142.
.
Hope this helps you to understand this type of operation a little better.
