Which function has the smallest x-intercept value, if it exists? O f(x) = 3x – 9
O F(x) = +4
O f(x) = Vx+1
Of(x) = x²

The smallest x-intercept is x = -1, from equation 3.

Step-by-step explanation:

The x-intercept value of a function happens when "y", or in this case f(x), is equal to 0. Therefore we need to analyze each equation by making f(x) = 0 and finding x.

(a)

(b)

Since this is a constant function for which f(x) = 4, then there will be no x-intercept.

(c)

(d)

From these options the smallest x-intercept is x = -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
