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.
-x -2 I think . 3-(-5)= -2 and 2x -3x = -x
Answer:
3(3x+2)

Answer:
P(t)= 100t + 150
Step-by-step explanation:
If the price for 6 hours of studio time is 600 dollars, that means every hour the studio is used it costs 100 dollars. Since the fixed fee is 150 dollars, that is added to the cost of how many hours the studio is used.

Answer:
= 6x² + 24x + 17
Step-by-step explanation:
g(x+2) = 6(x+2)² -7
= 6(x² + 4x + 4) - 7
= 6x² + 24x + 24 - 7
= 6x² + 24x + 17
