intercepts of f(x)=(x^2-9)/(x^2-4x-21)

intercepts

f (x) = \frac{x ^{2} - 9}{x ^{2} - 4 x - 21}

X Intercepts : (3, 0), Y Intercepts : (0, \frac{3}{7})

Solution steps

x -

axis interception points of

\frac{x ^{2} - 9}{x ^{2} - 4 x - 21} : (3, 0)

y -

axis interception point of

\frac{x ^{2} - 9}{x ^{2} - 4 x - 21} : (0, \frac{3}{7})

X Intercepts : (3, 0), Y Intercepts : (0, \frac{3}{7})

x^{3} + 3 x^{2} + 5 x + 7

f (x) = 36 x^{2}

\frac{x ( x - 2 )}{( x - 1 ) ^{2}}

y = \frac{1}{4} x + 5, (0, 2)

f (x) = \frac{x + 5}{x ^{2} - 10 x + 25}
