y = 0.5x + 1 x = -2, y = 0
x = -1, y = 0.5
x = 0, y = 1
x = 1, y = 1.5
x = 2, y = 2 Plot the points in the coordinate system, and draw the line, which is the line of the given equation.

A graph that has 1 parabolla that has a minimum and 1 positive line.
answer is 1

A straight line through the points (0, 1) and (-0.4, 0).
y = x2 + 2x + 1zeros are:0 = x2 + 2x + 10 = (x + 1)(x + 1)0 = (x + 1)2x = -1So that the graph of the function y = x + 2x + 1 touches the x-axis at x = -1.
