Finding Intercepts of Quadratic Functions
What are the intercepts of the function?
The x-intercepts are
Consider the function f(x) =
X-intercepts
0 = x2 + 12x + 11
0 = (x + 1)(x+ 11)
The y-interceptis
y-intercept
f(0) = (0)2 + 12(0)+ 11

Choose the graph that matches the following system of equations: 7x + 2y = −6 6x − 7y = 21 a line includes points negative 2 comma 4 and 0 comma negative 3. a line includes points 6 comma 2 and 0 comma negative 3 a line includes points 0 comma negative 3 and 6 comma 2. a line includes points negative 2 comma 1 and negative 3 comma 4 a line includes points 0 comma negative 3 and negative 1 comma 4. a line includes points 0 comma negative 3 and negative 1 comma 3 a line includes points 0 comma 3 and negative 1 comma negative 3. a line includes points 0 comma negative 3 and negative 2 comma 4.
