Question

_

Answer 1

y = 3x^2
put each pair of x, y values and see which one satisfies the function.

Answer 2

yes. The first coordinate is x. The second coordinate is y.

Answer 3

you are welcome.

Answer 4

y = 3x^2
First choice is (1,3)
put x = 1 and see if you get y = 3
y = 3x^2
x = 1
y = 3(1^2) = 3
So (1,3) satisfies the equation. That means (1,3) lies on the function h(x) = 3x^2

Answer 5

You should try each point in the answer. The last one also lies on the function.

Answer 6

No (1,9) would NOT work.
y = 3x^2
put x = 1 and you get y = 3 * (1^2) = 3 * 1 = 3 which is NOT 9. So (1,9) does NOT lie on the function.

Answer 7

No, (-1, -3) will NOT work.
y = 3x^2
put x = -1
y = 3 * (-1)^2 = 3 * 1 = 3 which is not -3. Therefore (-1,-3) does NOT lie on the function.

Remember, (-1)^2 = (-1) * (-1) = +1

Answer 8

Yes. I was answering two other questions....

Yes, the first and the last points lie on the function.

Answer 9

cool. you are welcome.
