Complete the table for each function.

1. f(x) = √x The x values are 0, 1,4 and 9. The corresponding y values that I got are 0, 1, 2 and 3.

2. g(x) = -1/4√ x The x values are 0, 1, 4, and 9. The corresponding y values that I got are 0, -1/4, -1/2 and -3/4

3. h(x) = √x - 2 The x values are 0, 1, 4, and 9. I couldn't seem to find y values for this.

Can you please check my work on numbers 1 and 2, and help me answer number 3? Thank you.

  1. 1, 2. Okay

    3. √0 - 2 = -2…

    √9 - 2 = 3 - 2 = 1

    I'll let you do the other two.

  4. Y values: -2, -1, 0, 1. Right?

    I'm not sure why I had so much trouble with this. I think I was making a minor mistake in my calculations that set everything off. Thanks for your help.
