What is the answer to this?

486

Step-by-step explanation:

We start by getting the quotient.

That is f(x) divided by g(x)

We have this as;

f(x)/g(x) = 2x^3/2 divided by x^1/4

By law of indices division, we have this as;

2 * x^(3/2-1/4)

= 2 * x^(1.5-0.25)

= 2 * x^(1.25)

= 2x^5/4

Insert x = 81

That will be;

2 * (81)^5/4

Multiplying this by 2, we have;

2 * 243 = 486

351.23

step-by-step explanation:

the answer is d

the answer is in the first quadrant, which make the y-int positive.

since the dots are going down, therefore the correlation is negative

i hope it is right.
