Question

For which value of x does the graph of y = 2x2 − 7x + 6 cross the x-axis?

Answer 1

Since the x axis is equal to the line y=0, we can set the function equal to 0 to figure out where it crosses the x axis:
0=2x^2 -7x +6
You can solve this by either factoring, graphing, or using the quadratic formula
