F(x) = -(x+7)² + 4
f(x) = -(x+7)(x+7) + 4
f(x) = -(x² + 7x + 7x + 49) + 4
f(x) = -x² - 14x - 49 + 4
f(x) = -x² - 14x - 45
True for f(x)

Answer:The maximum number of visits a member of the history museum can make for a total cost of $40 is 17
Step-by-step explanation:
Let x represent the number if visits that visits the person makes to the museum.
Let y represent the cost of x visits
A person can pay $6 for a membership to the history museum and then go to the museum for just $2 per visit. It means that the total cost, y for x visits will be
y = 2x + 6
For a total cost of $40, y = 40. So
40 = 2x + 6
2x = 40 - 6
2x = 34
x = 34/2 = 17
