Which equation below would result in the highest earnings, y, when the number of hours worked, x, is 20?
BartSMP [9]

Answer:

(B)    

Step-by-step explanation:

(A)The given equation is:

y=2x^2

Substituting the value of x=20, we get

y=2(20)^2

y=2(400)

y=800

(B) The given equation is:

y=2^x

Substituting the value of x=20, we get

y=2^{20}

y=1048576

(C) The given equation is:

y=2x+2

Substituting the value of x=20, we get

y=2(20)+2

y=42

(D) The given equation is:

y=|2x|

Substituting the value of x=20, we get

y=|2(20)|

y=40

Thus, the equation y=2^x results in the highest earning y.
