Graphing Exponential Functions:

If (-1, y) lies on the graph of y = 22x, then y =
Options:
A. -4
B. 1/4
C. 1

2/5

step-by-step explanation:

your answer is 125y5

the diagram shows you   triangle def with de=4, df=9 and de≠df≠ef.

the sum of the lengths of two triangles' sides are always greater than the length of the third side:

substitute sides lengths:

then 5< ef< 13 (option 3 is true).

def is a scalene triangle with all sides of different lengths (option 5 is true, option 2 is false).

answer: correct choices are 1, 3 and 5
