Use the graphing calculator to graph the quadratic function y = 2x2 – 6x – 8. which values are solutions of 0 = 2x2 – 6x – 8? check all that apply. –4 –1 0 1 4

x= -1 and x = 4

Step-by-step explanation:

We have to graph the quadratic function using the graphing calculator.

The graph has been attached.

Now, we have to find the solutions of the equation

For this, we see at which point (s) the graph intersects the x axis. The x coordinate of these points would be the solution.

From the attached graph we can see that the graph intersects the x-axis at (-1,0) and (4,0). Hence, the x-coordinate of these points would be the solution.

Thus, the solutions of the given equation are x= -1 and x = 4

x + 107

step-by-step explanation:

let's say that the number he had before the mistake was x. then, he will have 107 dollars more than this, so the answer is x + 107.
