Answer:
The answer to your question is below
Step-by-step explanation:
Data
function f(x) = x² + 2x - 8
-See the graph below
1) x-intercepts
We observe in the graph that there are no x-intercepts.
2) y-intercepts
We observe in the graph that the y-intercept is (0, 8). Point A
3) axis of symmetry
The axis of symmetry is the line that divides the parabola into two equal parts. This line is x = -1 (blue line)
4) The vertex is the lowest point of the parabola, this point is (-1, 7)
Point B in the graph.

The total cost of the meal is $30.02
Step-by-step explanation:
Given,
Cost of meal = $24.62
Tax = 6%
Tax amount = 6% of cost of meal
Cost after sales tax = 24.62+1.48 = $26.10
Tip = 15%
Tip amount = 15% of cost after sales tax
Total cost of meal = Cost after sales tax + Tip amount
Total cost of meal = 26.10+3.92 = $30.02
The total cost of the meal is $30.02
