Question

Use the image to answer the question.

A graph shows both the x-axis and y-axis, ranging from negative 10 to 10 in increments of 5. An upward parabola passes through all four quadrants.

(−1,43)

Answer 1

To determine which ordered pairs are part of the solution set for the equation y=5x^2−2, we can substitute the x and y values into the equation and solve for y.

Let's check each option:

1) (-1,3)
y=5(-1)^2-2
y=5(1)-2
y=5-2
y=3

The equation is satisfied, so (-1,3) is a solution.

2) (1,5)
y=5(1)^2-2
y=5(1)-2
y=5-2
y=3

The equation is not satisfied, so (1,5) is not a solution.

3) (-1,5)
y=5(-1)^2-2
y=5(1)-2
y=5-2
y=3

The equation is not satisfied, so (-1,5) is not a solution.

4) (-1,43)
y=5(-1)^2-2
y=5(1)-2
y=5-2
y=3

The equation is not satisfied, so (-1,43) is not a solution.

Therefore, the only ordered pair that is part of the solution set for the equation y=5x^2−2 is (-1,3).
