given that f(x) = 4x +1 and g(x) = x^2 -2,

which of the following is an expression for f(g(

a. 16x^2 + 8x - 1
b. x^2 + 4x - 1
c. 5x^2 - 1
d. 4x^2 - 7

d.

Step-by-step explanation:

The given functions are

and

We want to find the composition of the f and g.

We substitute into to obtain;

This simplifies to;

Hence the correct choice is d.

sorry, i can't understand your question. will later if you describe more clearly!

$3720

step-by-step explanation:

taxable income = $31000

as per the 2018-2019 us tax bracket, the tax rate is 12% for an individual whose taxable income is between $9,526 to $38,700.

so, the tax to be paid by him = 12% of 31000

= 0.12 * 31000     [12% converted to decimal as 0.12]

= $3720
