Find the x and y Intercepts f(x)=(5x^2-25x)/(-4x^2)

$f (x) = \frac{5 x^{2} - 25 x}{- 4 x^{2}}$

Find the x-intercepts.

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

$0 = \frac{5 x^{2} - 25 x}{- 4 x^{2}}$

Solve the equation.

Set the numerator equal to zero.

$5 x^{2} - 25 x = 0$

Solve the equation for $x$ .

Factor $5 x$ out of $5 x^{2} - 25 x$ .

Factor $5 x$ out of $5 x^{2}$ .

$5 x (x) - 25 x = 0$

Factor $5 x$ out of $- 25 x$ .

$5 x (x) + 5 x (- 5) = 0$

Factor $5 x$ out of $5 x (x) + 5 x (- 5)$ .

$5 x (x - 5) = 0$

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

$x = 0$

$x - 5 = 0$

Set $x$ equal to $0$ .

$x = 0$

Set $x - 5$ equal to $0$ and solve for $x$ .

Set $x - 5$ equal to $0$ .

$x - 5 = 0$

Add $5$ to both sides of the equation.

$x = 5$

The final solution is all the values that make $5 x (x - 5) = 0$ true.

$x = 0, 5$

Exclude the solutions that do not make $0 = \frac{5 x^{2} - 25 x}{- 4 x^{2}}$ true.

$x = 5$

x-intercept(s) in point form.

x-intercept(s): $(5, 0)$

Find the y-intercepts.

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

$y = \frac{5 {(0)}^{2} - 25 \cdot 0}{- 4 {(0)}^{2}}$

The equation has an undefined fraction.

Undefined

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

y-intercept(s): $None$

List the intersections.
