Question

Which of these shows the graph for the quadratic function.
y = 2x2 + 5x – 3?

Answer 1

What other choices are there?

Answer 2

Moar choices.

Answer 3

None of those are it, gotta be more

Answer 4

Is that equation you put 2x^2 + 5x - 3?

Answer 5

yes

Answer 6

Oh, then it's c.

Answer 7

C is right. Sorry for blurting the answer. You can check because the y-intercept is -3 (If you give a value of 0 for x).

Answer 8

thanks!

Answer 9

An easy way to see if the parabola is upwards or downwards is if the function is negative at the ^2 part.

For example: -2x^2 = n-shaped parabola
2x^2 = u-shaped parabola

Think of it as negative = sad face
positive = happy face :>
