Find the x and y Intercepts f(x)=-x(x-1)(x+2)^2

$f (x) = - x (x - 1) {(x + 2)}^{2}$

Step 1

Find the x-intercepts.

To find the x-intercept(s), substitute in $0$ for $y$ and solve for $x$ .

$0 = - x (x - 1) {(x + 2)}^{2}$

Solve the equation.

Rewrite the equation as $- x (x - 1) {(x + 2)}^{2} = 0$ .

$- x (x - 1) {(x + 2)}^{2} = 0$

If any individual factor on the left side of the equation is equal to $0$ , the entire expression will be equal to $0$ .

$x = 0$

$x - 1 = 0$

${(x + 2)}^{2} = 0$

Set $x$ equal to $0$ .

$x = 0$

Set $x - 1$ equal to $0$ and solve for $x$ .

Set $x - 1$ equal to $0$ .

$x - 1 = 0$

Add $1$ to both sides of the equation.

$x = 1$

Set ${(x + 2)}^{2}$ equal to $0$ and solve for $x$ .

Set ${(x + 2)}^{2}$ equal to $0$ .

${(x + 2)}^{2} = 0$

Solve ${(x + 2)}^{2} = 0$ for $x$ .

Set the $x + 2$ equal to $0$ .

$x + 2 = 0$

Subtract $2$ from both sides of the equation.

$x = - 2$

The final solution is all the values that make $- x (x - 1) {(x + 2)}^{2} = 0$ true.

$x = 0, 1, - 2$

x-intercept(s) in point form.

x-intercept(s): $(0, 0), (1, 0), (- 2, 0)$

Step 2

Find the y-intercepts.

To find the y-intercept(s), substitute in $0$ for $x$ and solve for $y$ .

$y = 0 ((0) - 1) {((0) + 2)}^{2}$

Solve the equation.

Remove parentheses.

$y = 0 (0 - 1) {((0) + 2)}^{2}$

Remove parentheses.

$y = 0 (0 - 1) {(0 + 2)}^{2}$

Remove parentheses.

$y = 0 ((0) - 1) {((0) + 2)}^{2}$

Simplify $0 ((0) - 1) {((0) + 2)}^{2}$ .

Subtract $1$ from $0$ .

$y = 0 \cdot - 1 {((0) + 2)}^{2}$

Multiply $0$ by $- 1$ .

$y = 0 {((0) + 2)}^{2}$

Add $0$ and $2$ .

$y = 0 \cdot 2^{2}$

Raise $2$ to the power of $2$ .

$y = 0 \cdot 4$

Multiply $0$ by $4$ .

$y = 0$

y-intercept(s) in point form.

y-intercept(s): $(0, 0)$

Step 3

List the intersections.

x-intercept(s): $(0, 0), (1, 0), (- 2, 0)$

y-intercept(s): $(0, 0)$

Step 4

Find the x and y Intercepts f(x)=-x(x-1)(x+2)^2
