Finding area under a curve

From [1,3]
2x^2 -4x +1

• Calculus -

is your curve y = 2x^2 - 4x + 1 ?
Is your region between the curve and the x-axis within your stated domain ?
Did you notice that the parabola has an x-intercept within your domain?

• Calculus -

its from 1 to 3 on the x axis including when it crosses underneath, you subtract that (its like negative area)
