(a) If you want to model the expenditure figures with a function of the form f(t) = at² + bt + c, would you expect the coefficient a to be positive or negative? Why? HINT [See "Features of a
Parabola" in this section.]
We would expect the coefficient to be negative because the curve is concave down.
We would expect the coefficient to be positive because the curve is concave down.
We would expect the coefficient to be positive because the curve is concave up.
We would expect the coefficient to be negative because the curve is concave up.
