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.

Step-by-step explanation:
The correct answer is

You can find this by first starting with the original question.

÷

Now to solve a division problem with fractions, you can always flip the second one and turn it into multiplying.

*

Now we can multiply numerator by numerator and denominator by denominator.

Then of course, we need to simplify. Since both are divisible by 3, we can divide both numbers by 3.
