Which function is a horizontal compression of its parent function f(x)=x^7 by a factor of 4? a - q(x)=(1/4 x)^7 b - r(x)=(4x)^7 c - s(x)=4x^7 d - t(x)=1/4 x^7 i think it’s b; check my answer

The function given to us is :

We want to see which function represents the horizontal compression of f(x) by a factor of 4

We can compress a function horizontally by multiplying the x by a constant number, in this case multiplying x by 4

So horizontal compression of

This matches with the option B =

Hence, your answer (B) is correct.

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

step-by-step explanation:

the answer is 2/54
