Answer 9

y= ½ x^2 is a parabola

if you are doing integral calculus, they assume you know geometry, trig, algebra, etc.

a parabola has a \( \cup\) shape. pick x=0, 1,2,3 and figure out the y values
plot the points, and connect the dots (knowing the shape is "cup-shaped" )
y=x is a line with slope=1, and y-intercept of 0
x=3 is a vertical line at x=3
