The weight of an ideal cut round diamond can be modeled by the polynomial f(d)=0.0071d^3−0.090d^2+0.48d , where d is the diameter of the diamond. Find the domain and range of the function in the context of the situation. A)The domain and range are both all real numbers.
B)The domain is {d|d≥0} , and the range is {f(d)||f(d)≥0} .
C)The domain is {d|d≥0} , and the range is all real numbers.
D)The domain is all real numbers, and the range is {f(d||f(d)≥0)} .

is there a picture

step-by-step explanation:

answer: c, the green line

step-by-step explanation:

there is no black line, eliminate b.

simple interest implies periodic payments, but the red line shows no payments, eliminate d.

simple interest has equal payments. if paid say every day, the graph is about a straight line (actually a stairstep).

the yellow line is not straight, eliminate a.

check: the green line is straight, answer is c.

simple interest with positive interest rate gives a straight line sloping up to the right. green line:

g(t) = $100 + ($200-$100) ÷ (20 years) × (t years)

= $100 + (4%/year) × ($100)(t years)

incidentally, the yellow line curving upward represents continuously compounded interest

y = $100 × 2^(t years / (14 assuming the yellow line hits $200 at 14 years. 2^0 is 1, so y(0) = $100; 2^(14/14) is 2, so y(14) = $200.
