It’s a function, the only thing missing is (b) in the formula y=Mx+b. This just implies the y intercept of the function is at (0,0), since (b) = 0.

Answer:
The correct option is C.
Step-by-step explanation:
The function has axis of symmetry at
, it represents that the parabola is along the x-axis and the standard form of parabola is

Where, a is scale factor and (h,k) is vertex.
The maximum or minimum value of a quadratic function is the vertex of parabola. So, vertex of parabola is (6,4).

The y-intercept of the function is (0,-32)




Therefore required equation of parabola is




Therefore option C is correct.
Answer:
Step-by-step explanation:
Decreasing rate = 12% = 0.12
y = 2400 * (1- 0.12)^x = 2400*(0.88)^x
x = 8 years
