Question

At how many points does the graph of the function intersect the x-axis?

Answer 1

hint: use the quadratic equation

Answer 2

@Vocaloid thanks!

Answer 3

yeah, no problem

if b^2 - 4ac is positive, there are 2 solutions. if it's 0, there's 1 solution, if it's negative, there are 0 solutions

Answer 4

in this case, a = 16, b = -8, and c = 1

so what is b^2 - 4ac?

Answer 5

0 @Vocaloid

Answer 6

good!

so there's only 1 solution to the equation, and the graph only crosses the x-axis once

Answer 7

@Vocaloid thank u so much!
