Step-by-step explanation:
Lest's organize the table values of our function first:
x y
-6 -4
-3 -2
0 0
3 2
The simplest kind of of function is a linear function of the form
where
is the slope and
is the y-intercept. Let's us check if our function is a linear one finding its equation and checking that all points are in the line.
The first step to find a linear equation is find the slope of the line; to do it, we are using the slope formula:
where
We know from our table that the first and second points are (-6, -4) and (-3, -2) respectively, so
,
,
, and
.
Replacing values:
Now that we have the slope of our line we can use the point slope formula to complete our linear function:
where
Replacing values:
Now, to check if our function is valid, we can either check if each point satisfies the rule
, or we can graph it and check if each lies is in the graph.
Let's check both:
We already know that points (-6, -4) and (-3, -2) satisfy the rule (after all, those were the point we used to came out with the rule in the first place), so we just need to check the points (0, 0) and (3, 2)
- For (0, 0):
The point satisfies the rule.
- For (3, 2):
The point satisfies the rule.
Since all the points of our table satisfies the rule
, we can conclude that the rule describing the function shown is
.

14430 pounds
Step-by-step explanation:
Given that:
cost of ring: 13000
percentage increase: 11%
So, to find the new cost, we have to find the increase cost, in pounds:
11 / 100 times 13000 = 1430 pounds.
NOW to calculate the new cost, we add the increase cost to the original:
13000 + 1430 = 14430
