which of the following represents the parent function of
y = -3x + 5 + 5x^2 ?

a : y = x
b : y = -2x
c : y = |x|
d : y = x^2

D

Step-by-step explanation:

It is y=x^2 because the function you stated is a parabola/quadratic function. You can see that y = 5x^2 +3x + 5 can be made by multiplying D by 5, and adding 3x and 5. If a function has an x^2, y = x^2 is its parent function.

the answer would be 1 1/72

step-by-step explanation:

you can rewrite the equation by separating the parts and then solving individually:

10-9=1

1/8 - 1/9=

find l c d and then combine:

1 1/72
