Question 112401: How would the following equations look on a graph? I would like to double check my answers, thank you.
y=x^2-4x
y= -x + 1
y =x + 1
and
y =2x^2

Here are the four graphs:
.
First the graph of y = x^2 - 4x
.
graph%28600%2C600%2C-20%2C20%2C-20%2C20%2Cx%5E2-4x%29
.
Next the graph of y = -x + 1
.
graph%28600%2C600%2C-20%2C20%2C-20%2C20%2C-x%2B1%29
.
Then the graph of y = x + 1
.
graph%28600%2C600%2C-20%2C20%2C-20%2C20%2Cx%2B1%29
.
and finally the graph of y = 2x^2
.
graph%28600%2C600%2C-20%2C20%2C-20%2C20%2C2x%5E2%29
.
