the correct answer option is d. 5, -4.
we are given the following equation and we are to solve it using the quadratic formula:
re-arranging this equation in order of decreasing power:
using the quadratic formula:
substituting the given values in the formula to get:
y axis. we never moved off the origin in the x direction, so we are on the y axis.
the x value is 0. this means starting at the origin and moving to the right zero units. now we move up 8 units. we are moving up 8 units. we are on the y axis.
