The axis of symmetry for a function in the form f(x)= x^2+4x-5 is x=-2 what are the coordinates for the vertex of a graph

The equation represents a quadratic function. The graph of a quadratic function is a special type of U-shaped curve called a parabola. By plotting this function, we get the graph of the parabola shown in the figure below.

So, from the figure you can see that this point is and since this point is a minimum.

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
