Priya wants to sketch a graph of the polynomial f defined by f(x) = x3 + 5x2 + 2x – 8. She knows f(1) = 0, so she suspects that (x - 1) could be a factor of x3 + 5x2 + 2x -- 8 and
writes (x3 + 5x2 + 2x - 8) = (x - 1)(? x² +?x+?) and draws a diagram.
X

1.
Finish Priya's diagram.
2.
Write f(x) as the product of (x - 1) and another factor.
3.
Write f(x) as the product of three linear factors.
4.
Make a sketch of y = f(x).

i dont get it. where are the "descriptions"?

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.
