Will give brainliest when the function f(x) = 4(2)x is changed to f(x) = 4(2)x − 13, what is the effect? -there is no change to the graph because the exponential portion of the function remains the same. -the x-intercept is 13 spaces higher. -the y-intercept is 13 spaces lower. -all input values are moved 13 spaces to the left.

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.

Comment on notation

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

where is the rest of the
