Answer:
4
Step-by-step explanation:
the correct answer is number 4
if X = 2 ==> 2x -5 = 2(2) -5 = 4 - 5 = -1
The y-in is -6
The x- in is -1 and -6
The vertex is (-3.5,-6.25)
The axis is -3.5
Amplitude:4
Equation of Midline: 2
Period of function:3
Function shifted left:0.5
Function shifted up: 2
60 = 0.20x
60/0.20 = x
300 = x <== so 60 minutes is 20% of 300 minutes
