Answer:
The graph in the attached figure
Step-by-step explanation:
we have
Using a graphing tool
see the attached figure
This is the equation of a vertical parabola open downward
The vertex is the point (3.25,225) (a maximum)
The zero's of the function or the t-intercepts are the points (-0.5,0) and (7,0)
The h-intercept of the function is the point (0,56)
The domain of the function are all real numbers
The range of the function ----> All real numbers less than or equal to 225
Answer:
Step-by-step explanation:
we have
we know that
The equation of a vertical parabola into vertex form is equal to
where
(h,k) is the vertex of the parabola
and the axis of symmetry is equal to
In this problem we have the axis of symmetry
so
the x-coordinate of the vertex is equal to
therefore
For -----> one unit to the right of the vertex
Find the value of
For -----> one unit to the left of the vertex
Find the value of
Remember that
------> the x-coordinates are at the same distance from the axis of symmetry
so
------> solve for b
