<u>Given</u>:
The given expression is
We need to determine the simplified value of the given expression.
<u>Simplification</u>:
Since, the given expression is in the form of , the given expression can be simplified using the identity
Comparing the given expression with the identity, we get;
and
Using this in the identity, we get;
Simplifying, we get;
Thus, the simplified value of the given expression is
Hence, Option c is the correct answer.
You have added -13 to every function value, so every point on the graph is 13 "spaces" lower. The y-intercept is one such point, so ...
-The y-intercept is 13 spaces lower.

<em>Comment on notation</em>
In plain text an exponent is preceded by a caret (^). If the exponent has arithmetic involved (addition, subtraction, multiplication, division), then the entire exponent needs to be enclosed in parentheses. When an exponential term that has a constant base is multiplied by another constant, then some sort of multiplication indicator is useful. Your expressions might be written ...
... f(x) = 4·2^x
... f(x) = 4·2^x - 13 . . . . . . or, better, f(x) = 4(2^x) - 13 . . so it is clear -13 is not part of the exponent
