Using the graph of the function y = x ^ 2, the y-values corresponding to the x-values of 0.75; -1.25; 1.25; -2.5; 2.5;

1.y = x ^ 2

When x = 0.75, y = (0.75) ^ 2, that is, x = 0.5625,

2.y = x ^ 2

For x = – 1.25, y = (- 1.25) ^ 2, that is, x = 1.5625,

3.y = x ^ 2

For x = 1.25, y = (1.25) ^ 2, that is, x = 1.5625,

4.y = x ^ 2

For x = – 2.5, y = (- 2.5) ^ 2, that is, x = 6.25,

5.y = x ^ 2

For x = 2.5, y = (2.5) ^ 2, that is, x = 6.25;

Answer: x = 0.5625, x = 1.5625, x = 1.5625, x = 6.25, x = 6.25.
