Answer:

Step-by-step explanation:

Quadratic function is a function that can be described by an equation of the form fx = ax2 + bx + c, where a ≠ 0.

Example:

1. Use the graph of y = x2 + x - 6 to solve x2 + x - 6 = 0.

2. Use the graph of y = -x2 + 4 to solve -x2 + 4 = 0.

3. Use the graph of y = x2 -2x + 1 to solve x2 -2x + 1.

Margaret is planning a wedding reception. She wants to spend less than her budget of $5,748, and Margaret has already spent $2,4
noname [10]

Answer:

She can invite 109 guests and be right on top of budget. If she wants to spend less than her budget though she can only invite 108 people.

Step-by-step explanation:

First you have to subtract 5,748 - 2,478 which is 3270. Next you have to divide 3270 by 30 because each person costs 30 dollars. 3270 divided by 30 is 109.

I hope this helps! Please mark me brainliest if I am correct! Have a nice day!
