The function for the interest owed would be
15 + 0.01(x – 1000) = 15 + 0.01x – 10 = 5 + 0.01x

The function for the interest owed would be

? if 0 ≤ x ≤ 1000

g(x) = ? if x 1000

Can you find these?

Question

The function for the interest owed would be
15 + 0.01(x – 1000) = 15 + 0.01x – 10 = 5 + 0.01x

The function for the interest owed would be

?   if       0 ≤ x ≤ 1000

g(x) =             ?   if              x > 1000

Can you find these?

mertsj · Answer

g(0)=5 and g(1000)=15 so if 0<=x<=1000,  5<=g(x)<=15

mertsj · Answer

and if x>1000, g(x)>15

mertsj · Answer

$$if,  0\le x \le1000, 5\le g(x)\le15$$

mertsj · Answer

$$if, x >1000, g(x) >15$$
