Which of the following parabolas opens upward and appears narrower than y = -3x^2 + 2x - 1?
a. y = 4x^2 - 2x - 1
b. y= -4x^2 + 2x - 1
c. y = x^2 + 4x
d. y = -2x^2 + x + 3

Okay, so y = -3x^2 +2x -1 is represented in the first attached image.

Notice it's steep angle.

The graph of answer choice "D" angles downward, so that can't be the right answer.

The graph of answer choice "C" is angled upward, but at a vey wide angle

The graph of answer choice "B" is angled downward once again.

That leaves us with graph A [picture of graph included], which opens upward and appears narrower.

Your best answer choice is A

Hope that helps!

5x + 5

step-by-step explanation:

you should always add the diagrams and graphs we cannot see. this particular question is kind of borderline because we can make a graph for you.

(f + g)x = -x^2 +3x + 5 + x^2 + 2x

(f + g)x = 5x + 5

the graph of z = 5x + 5 is shown below. always use desmos when in doubt.
