Answer:
0.037037037037037 i think
Step-by-step explanation:
F(x) = 5x
for f(7) you replace x with 7 so it will be : f(7) = 5(7) = 35
Maximum value : x=-4
The graph of the parabola opens down, since the value of a (-2) is a negative coefficient. This means the parabola has a maximum value, not a minimum value. The vertex of the parabola is -4, which is the maximum value of the graph.
