About functions: I need help with these two. 1. Being a Real number. Being f the function, with the domain IR (real numbers), defined by:
f(x) = a(x-3)(x+2)
Knowing that the image of 0 is 18, determine the value of a.

2. Being f the function with the domain IR (real numbers), defined by:
f(x) = x³-6x²+11x-6
Determine all the zeros of the function.

step-by-step explanation:

the final amount you will pay is $68.04.

the tip is determined by the pre-tax amount, so we calculate the tip based on the original bill, not after we've added sales tax.

to find the tip:

we can divide 54.00 by 100 to get 1% of 54. then we multiply that by 18.

54 / 100 = .54

.54 x 18 = 9.72

tip = 9.72$

to find the tax:

we can divide 54.00 by 100 to get 1% of 54. then we can multiply that by 8 to get 8%.

54 / 100 = .54

.54 x 8 = 4.32

tax= 4.32

now we can add the tip and tax to the bill to get our total.

54 + 9.72 + 4.32 = 68.04

total: $68.04
