Answer: There's an increasing interval between -1 and 1
While x goes from -1 to 1, the value of y increases (from -2 to 2).
Answer:
I believe the answer ur looking for is 3 (D)
Step-by-step explanation:
11x2 would be your answer.
Answer:
Step-by-step explanation:
The common ratio is 3, so multiply the numbers of the pattern by 3. So 1x3 is 3, 3x3 is 9, 9x3 is 27, 27x3 is 81, 81x3 is 243, and just continue until you're on the 7th number; 1 was the first, 3 was the second and 9 was the third.
Answer:
A) 
B) The value of f(-3) is 8
C) The value of t is 6
Step-by-step explanation:
* Lets explain how to solve the problem
- The relation is 3r + 2t = 18
- To change the relation as a function of f(t) you must to find r in terms
of t that means put r in one side and the others in the second side
A)
∵ 3r + 2t = 18
- Subtract 2t from both sides
∴ 3r = 18 - 2t
- Divide each side by 3
∴ r = 18/3 - 2t/3
∴ r = 6 - 2/3 t
- Change the equation to a function by using the function notation
∵ r = f(t)
∴ 
B)
- To evaluate f(-3) substitute t by -3 in f(t)
∵ 
∴ 
∴ f(-3) = 8
* The value of f(-3) is 8
C)
- Solve f(t) = 2 means find the value of t when r = 2
∵ 
∵ f(t) = 2
∴ 
- Subtract 6 from both sides
∴ 
- Multiply both sides by 3
∴ -12 = -2t
- Divide both sides by -2
∴ t = 6
* The value of t is 6
