Answer:
The answer is B
Step-by-step explanation:
First you should make a table to explain it better to yourself. Make 2 columns named Domain(Input) and Range(Output). Now put your ordered pair in the range area. Now calculated the function by replacing X with the range. Calculate.
The range is { -1,3,7,11,15}
The range is just the output values
f(-2) = 4(-2) +7 = -8+7 =-1
f(-1) = 4(-1) +7 = -4+7 = 3
f(0)= 4(0) +7 = 7
f(1) = 4(1) + 7 = 11
f(2) = 4(2) +7 = 8+7 = 15
1/5
y = kx where k is the constant of proportionality
6 = k 30
Divide each side by 30
6/30 = k 30/30
1/5 = k
The constant is 1/5
27
Use exponent laws
1/3^-3 = 3^3 = 27
y maximum is at 1 for both the points (4,1) and (-4,1)
