Answer:
6/7
Step-by-step explanation:
2/3X9/7
simplify 9 by 3
which equals:
2/1X3/7
=6/7
Something funny is that the x value of the vertex lies directl in the middle of the x intercepts
so
we see the x intercepts or 0's at x=8 and 2
the average is x=5
so find f(5) to find the y value of the vertex
f(5)=(5-8)(5-2)
f(5)=(-3)(3)
f(5)=-9
vertex is at (5,-9)
the actual way the teacher wants is to expand then compltete the square to get into the form f(x)=a(x-h)^2+k where the vertex is (h,k)
but whatever
verrtex is at (5,-9)

Answer:
Step-by-step explanation:
Example of a linear function: y = -5x + 2. Note that both x and y are to the first power: y^1 and x^1.
Example of a nonlinear function: y = 2x^2 - x - 13. Here x is to the second power (which automatically makes this a nonlinear function).
