Applications: Integration test questions

1

Find the area between the curve \(y = {x^3}\) and the \(x\) axis.

Area under the x-axis for y=x cubed.

2

The diagram shows the area bounded by the curves \(y = {x^3} - 3{x^2} + 4\) and \(y = {x^2} - x - 2\) between \(x = - 1\) and \(x = 2\).

Represent the shaded area as an integral.

Area between graphs y=x^3-3x^2+4 and y=x^2-x-2

3

Find the area enclosed between the two curves in question 2.

Area between graphs y=x^3-3x^2+4 and y=x^2-x-2

4

Find the coordinates of P and Q.

Area between the graph y=(x+2)(x-1)(x-2) and the y-axis before point P, and under the x-axis between points P and Q

5

Find the area enclosed between the curve and the \(x\)-axis in question 4.

Area between the graph y=(x+2)(x-1)(x-2) and the y-axis before point P, and under the x-axis between points P and Q

6

A curve for which \(\frac{{dy}}{{dx}} = 3{x^2} + 1\) passes through the point \(( - 1,2)\).

Express \(y\) in terms of \(x\).

7

Find an expression for \(f(x)\) such that \(f\textquotesingle(x)= 4{x^3} - 1\) and \(f(2) = - 1\).
