A skateboard manufacturer finds that the cost $C of making x skateboards per day can be modelled by the function C(x) = ax
2+bx+c

If 50 skateboards are made in a day, the cost of production is $1544.
The manufacturer noticed that making 12 skateboards in a day minimizes the cost of
production to $100.
a) Write C(x) in the vertex form. Hence, find the values of a, b and c.
b) What is the cost of production if no skateboards are made in a day?
c) What is the number of skateboards made in a day for a cost of production of $116?
d) What is the number of skateboards made in a day for a cost of production of at most $116?

Which of the statements about the graph of the function y = 2x are true? check all of the boxes that apply. the domain is all real numbers x because the exponent of 2 can be any real number when the x-values increases by 1 unit, the y-value multiplies by 2. the y-intercept is (0, 1). the graph never goes below the x-axis because powers of 2 are never negative. the range is all real numbers.
