Answer:
f^-1(x)=3x
Step-by-step explanation:
y=x/3
to get the inverse function, exchange x and y,
x=y/3
solve for y, y=3x
f^-1(x)=3x
Answer:3
Step-by-step explanation:
Answer:
A: y = -2x^2
Step-by-step explanation:
The parent function would be y = x^2 since it is a parabola.
Since the function has a vertical stretch by 2, y = 2x^2.
Finally, the function is inverted so the final equation would be y = -2x^2
They will have to pay $7.50. And you just multiply 0.15 times 50.
