The given graph is a downward parabola.
The roots of the equation is -2 and -8, and the vertex is (-5,7).
The general root form of parabola will be,
a(x-(-2))(x-(-8))=a(x+2)(x+8).
The value of a can be determined from the coordinate of vertex,

Thus, the required quadratic is,

The value of f(-6) can be determined as,

Thus, the requried value of f(-6) is 6.22.
The slope of CD is -3. Bc if it was 3 as in the answer above, then the so called "parallel" lines would intersect.
the answer is 8 G(×) =0 interpret something like that but yeah

Answer:
49
Step-by-step explanation:
substitute b = - 6 and c = 7 into the expression and evaluate
c - 7b = 7 - (7 × - 6) = 7 - (- 42) = 7 + 42 = 49
