Consider the function f(x)=2^x . what effect does multiplying the output by 2 have on the graph of the function? a. stretches the graph vertically by a factor of 2. b. compresses the graph horizontally by a factor of 12 . c. compresses the graph vertically by a factor of 12 . d. shifts the graph left 2 units. e. stretches the graph horizontally by a factor of 2. f. shifts the graph up 2 units.

A

Step-by-step explanation:

A vertical stretch of a function means the output values have changed by a factor or multiplication by a number. Recall, an exponential function has the basic form  

.  

If our equation is , then a=1. To stretch it vertically by a factor of 2, we multiply a by 2. So 1(2)=2. The value of a now becomes 2.  This means the output values are doubled each time and the function increase much faster and stretches vertically.

 this is A.

answer

see attachment

explanation

the given function is

this function has y-intercept at

-4 and a slope of 2.

note that, the graph has a positive slope.

the graph that represents this function is the straight line that moves upward from left to right.

the graph touches the y-axis at -4.

the correct choice is the graph shown in the attachment.

50-38=12
