Question

What are the intercepts of the function?

The x-intercepts are
Consider the function f(x) = x2 + 12x + 11.
x-intercepts:
0 = x2 + 12x + 11
0 = (x + 1)(x+ 11)
The y-intercept is
y-intercept:
fo) = (0)2 + 12(0) + 11

Answer 1

x-int: (-1, 0), (-11, 0)

y-int: (0, 11)

Explanation:

To find x-int, set equation equal to 0:

x² + 12x + 11

(x + 1)(x + 11)

x = -11, -1

To find y-int, set x = 0

f(0) = 0² + 12(0) = 11

f(0) = 11
