Find the intercepts. Y = X^2 – 5X – 10?

Question

Find the intercepts. Y = X^2 – 5X – 10

Answer 1

x-intercepts when y=o (the zeros)
x^2 - 5x - 10 = 0 does not factor, so use quadratic eqn
a=1 b= -5 c= -10

x = (5+/- sqrt(25-4(1)(-10) ) ) / 2
x= (5+/- sqrt 65) /2

Answer 2

What intercpet, X or Y?

If you want X intercept, plug zero into Y and solve for X
If you want Y intercept, plug zero into X and solve for Y
