SOLUTION: Ehhhhh i dont like graphs, but most people do. everytime i plug in some numbers and then graph it, it ends up to be a straight line instead of a U shape: Parabola Exploring Quad

: Ehhhhh i dont like graphs, but most people do. everytime i plug in some numbers and then graph it, it ends up to be a straight line instead of a U shape: Parabola
Exploring Quadratic Graphs:
8. y = -1/3x^2
14. f(x) = x^2 + 2
18. y = -2x^2 + 2
please and thank you! you dont have to do all three. This question is from textbook texas algebra 1

Exploring Quadratic Graphs:
8. y = -1/3x^2
If x = 0, y = 0
If x = 1, y = -1/3
If x = -1, y = -1/3
If x = 2, y = -4/3
If x = -2, y = -4/3
etc.
------------------------

14. f(x) = x^2 + 2
If x = 0, y = 2
If x = 1, y = 3
If x =-1, y = 3
If x = 2, y = 6
If x =-2, y = 6
etc.
Cheers,
Stan H.
