Answer:
Step-by-step explanation:
The value of the function f(x) at x=a can be determined by substituting a instead of x into the function expression.
1. When x=-1, then
f(-1)=2\cdot (-1)^3-3\cdot (-1)^2+7=-2-3+7=2.
2. When x=1, then
f(1)=2\cdot 1^3-3\cdot 1^2+7=2-3+7=6.
3. When x=2, then
f(-1)=2\cdot 2^3-3\cdot 2^2+7=16-12+7=11.

Answer:
Kelly will still have more money than Luis
Kelly will have 25% more
Step-by-step explanation:
Let x represent the amount of money Kelly has and y, Luis
Luis has $40
and Kelly has 50% more money than Luis
Therefore, Kelly has;
50% of $40 + $40
= 0.5*40 + 40
= $60
If Luis gets $8 more, Luis will have;
$8 + $40 = $48
since Luis' $48 is less than Kelly's $60, Kelly will still have more money than Luis
Difference in their money = $60 - $48 = $12
Therefore, Kelly will have;
12/48 * 100 more than Luis
= 25% more
