Which of the following has a graph that is wider than the graph of y=3x^2+2?

A) y=3x^2+3
B) y=0.5x^2+1
C) y=-4x^2-1
D) y=4x^2+1

Would the answer be B?

46 answers

at x = 0, B is below
at all other points, B is below
so yes, right, B is wider.
In a typical function
y=ax²+k

k will shift the graph up and down, so does not affect the width.

a is the vertical stretching factor.
The greater its absolute value, the narrower the graph gets.

A negative value of a will flip the graph about the x-axis, but will not affect its width.

So for example,
y1=x² is wider than
y2=-2x² because |2|>1, so y2 is narrower (or y1 is wider than y2).

REAL ANSWERS

1) C. - (1,-4)
2) B. - (0.5x²+1)
3) D.
4) A. - f(x) = -10x², f(x) = 2x², f(x) = 0.5x²
5) D. - It shifts the vertex of the graph vertically

Hope this helped everyone out there!
Thats some straight dedication on number 4 tehe lol
Tehe is right!
C. (1, –4)
B. y = 0.5x² + 1
D. The vertex is (0,-4.5)
A. f(x) = –10x², f(x) = 2x², f(x) = 0.5x²
@i hate the school system, so i help you get through it as easy as possible
Um, for question 4, you put A., but the response with A. you have here isn't right. I clicked on the one with the response that you said. (f(x) = 0.5x^2, f(x) = -10x^2, f(x) = 2x^2). So i got it wrong. Only because you put the wrong response on A.

1) What is the vertex of the parabola?
- C, (1, -4)

2) Which of the following has a graph that is wider than the graph of y = 3x^2 + 2?
- B, y = 0.5x^2 + 1

3) Which graphs represents the function y = -2x^2 - 5?
- D, all the 4s curve at the bottom of graph

4) What is the order from narrowest to widest graph, of the quadratic functions f(x) = -10x^2, f(x) = 2x^2, f(x) = 0.5x^2
- A, f(x) = -10x^2, f(x) = 2x^2, f(x) = 0.5x^2

5) Use a graphing calculator to find the y-intercept and x-intercepts of the function: y = 0.5x^2 + 2x + 1
- B, y-intercept: -1; x-intercepts: -3.414 and -0.586

Hope this clears everything up!
CONNEXUS UNIT 5 LESSON 1 THANKS BUT I GOT 5 WRONG BCUZ THEY CHANGED THE QUESTION so here are the current answers:

1) What is the vertex of the parabola?
- C, (1, -4)

2) Which of the following has a graph that is wider than the graph of y = 3x^2 + 2?
- B, y = 0.5x^2 + 1

3) Which graphs represents the function y = -2x^2 - 5?
- D, all the 4s curve at the bottom of graph

4) What is the order from narrowest to widest graph, of the quadratic functions f(x) = -10x^2, f(x) = 2x^2, f(x) = 0.5x^2
- A, f(x) = -10x^2, f(x) = 2x^2, f(x) = 0.5x^2

5) Compare the parent function f(x)=x^2 to the quadratic function f(x)= -2x^2 -6
-D, It shifts the vertex of the graph vertically
