A)
Which of the following has a graph that is wider than the graph of y = 3x² + 2?
(1 point)
y = 3x² + 3
y = 0.5x² + 1
y = –4x² – 1
y = 4x² + 1
Which of the following has a graph that is wider than the graph of y = 3x² + 2?
(1 point)
y = 3x² + 3
y = 0.5x² + 1
y = –4x² – 1
y = 4x² + 1
The graph that is wider than the graph of y = 3x² + 2 is y = 0.5x² + 1.
A)
What is the order, from narrowest to widest graph, of the quadratic functions f(x) = –10x², f(x)
= 2x², f(x) = 0.5x²
(1 point)
f(x) = –10x², f(x) = 2x², f(x) = 0.5x²
f(x) = 2x², f(x) = –10x², f(x) = 0.5x²
f(x) = 0.5x², f(x) = 2x², f(x) = –10x²
f(x) = 0.5x², f(x) = –10x², f(x) = 2x²
What is the order, from narrowest to widest graph, of the quadratic functions f(x) = –10x², f(x)
= 2x², f(x) = 0.5x²
(1 point)
f(x) = –10x², f(x) = 2x², f(x) = 0.5x²
f(x) = 2x², f(x) = –10x², f(x) = 0.5x²
f(x) = 0.5x², f(x) = 2x², f(x) = –10x²
f(x) = 0.5x², f(x) = –10x², f(x) = 2x²
The order, from narrowest to widest graph, of the quadratic functions is: f(x) = 2x², f(x) = 0.5x², f(x) = -10x². Therefore, the correct answer is: f(x) = 2x², f(x) = 0.5x², f(x) = -10x².
