If the function y=2^x is replaced by y=2^-x, then the new graph can be described as a reflection of y=2^x

(1) in the x-axis

(2) in the y-axis

(3) in the line y=x

(4) through the origin (0,0)

-13

step-by-step explanation:

f(x)=2x-5 for f(-4)

f(-4)   means let x=-4

f(-4) = 2(-4) -5

f(-4) =-8-5

      = -13

a

step-by-step explanation:

the answer is a

8

step-by-step explanation:

sample answer: you can determine whether each element of the domain is paired with exactly one element of the range. for example, if given a graph, you could use the vertical line test; if a vertical line intersects the graph more than once, then the relation that the graph represents is not a function.
