Question

Y = x2 + 1 i am so confused if is increases, or it does not cross the orgin, or its not a line, or one input

Answer 1

Explanation:

The more common way of writing this equation would be the following way

y = 2x + 1

This is a linear equation in slope-intercept form, meaning that 2 is the slope when graphed while 1 is the point where the line intercepts the y-axis when x is equal to 0. This equation has only 1 input (x) and 1 output (y). You can see the equation graphed in the picture attached below. As you can see the line crosses the y-axis at point (0,1) and crosses the x-axis at point (-0.5,0)
