If F(x)= 1/4 X+3 then F-1(X)= ???

Step-by-step explanation: That would mean that f(2) and f(4) both equal 3, and one-to-one ... the function defined by f(x)=2x + 2, and let g : R ! R be the function defined by g(x) = 1. 2 x 1. Then ... Use that f is an invertible function and that f-1. (1) = -2 f-1(2) = 3 f-1(3) = 2 f-1(4) = 5 f-1.

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

however, log(15/7) is equivalent to log(15) - log(7)

i'm using the rule log(x/y) = log(x) - log(y)
