Answer:
Rate of change = 2
Step-by-step explanation:
From the image attached, we are given a parabola which opens upwards with many points marked on the curve.
We are asked to find the rate of change for the interval between 3 and 6 on the x axis.
Now, rate of change of any function f(x) from a to b is given by the formula ;
Rate of change = [f(b) - f(a)]/(b - a)
For this question, a = 3 and b = 6
f(3) is simply the y-value when x is 3. On the graph, f(3) = -2
Similarly,f(6) = 4
Thus;
Rate of change = [4 - (-2)]/(6 - 3)
Rate of change = 6/3
Rate of change = 2
Answer:
3rd option
Step-by-step explanation:
So we are given the following points:
(1,5)
(2,15)
(3,45)
(4,135)
This is a geometric sequence because there is a common ratio, 3. That is you can keep multiply 3 to a previous y-coordinate to get the next y-coordinate.
The formula for a geometric sequence is
where is the first term and r is the common ration.
So we have
.
If you want to know the fifth term, just plug in 5:
