G(x) is 0 when x = -3 and 3 so g(x) passes though x axis at x = -3 and x = 3
At x = 0 g(x) = 9 so it also passes through (0,9) and its symmetrical about the y axis The vertex is at (09)
so we can write it as g(x) = a(x - 0)^2 + 9
plugging in the point (2,5) 5 = 4a + 9
4a = -4 so a = -1
and the equation of the parabola is g(x) = -x^2 + 9
Answer:
its 0 and 2 and -3(im pretty sure)

f^-1 (x) = −x + 1
120 - 22 = 98. 98 / 15 = 6.533333. Because you want the minimum, and he can't get paid during 0.53333 of a week, Tom must walk the dog for a minimum of 7 weeks.
