c. 43
d. 49

Given a quadratic equation

the discriminant is defined as

In your case, you have

Plug those values in the discriminant definition to get

$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.
