Answer:
vertex is (6 , -9)
points are (9,0) and (3,0)
Step-by-step explanation:
Given quadratic function
We have to plot the given quadratic function.
Consider the Given quadratic function
The general form of quadratic function is given
Where, (h, k) is vertex , given and
Thus, for given quadratic function
a = 1 , b= -12 , c = 27
Thus,
that is f(12) = (6)^2 - 12× 6 +27 = 36 - 72 + 27 = - 9
Thus, given quadratic function in standard form is
Thus, vertex is (6 , -9)
For second point put , we get,
Thus, and
thus, points are (9,0) and (3,0)
Graph is attached below.
