A function is increasing if it "points upwards".
Think that you have two inputs
(think of them as being very close to each other). A function
is increasing if
![f(x_1)](https://tex.z-dn.net/?f=%20f%28x_1%29%3Cf%28x_2%29%20)
So, smaller input, smaller output.
So:
- In the first segment on the left, the function is decreasing: if you move with little steps rightwards, the output will get smaller and smaller (the function points to the right bottom)
- In the second segment, the line is constant (it's horizontal). This means that even if you consider a larger input, the output reimains the same
- In the third segment, the function is increasing: if you consider a larger input, the output will be larger as well: the function points to the top right.
- In the fourth segment, the function is decreasing again (look at the first bullet point)
So, the function is increasing in the third segment, which is delimited by
![-2\leq x \leq 3](https://tex.z-dn.net/?f=%20-2%5Cleq%20x%20%5Cleq%203%20)
The answer is found by using the distributive property.
6(6a-4b)
36a-24b
Answer:
$18
Step-by-step explanation:
Let's subtract the lunch from the trip total to get the remainding cost!
36.50 - 9.50 = $27
Now let's set up an equation to figure out the amount of the entrance ticket and the gift coupon!
let's have x = the entrance ticket
27 = x + 1/2(x) -----------> 1/2 is next to x, because the gift coupon is 1/2, or 50% of the entrance ticket! Now solve for x!
27 = 3/2x
(2/3) 27 = 3/2x (2/3)
18 = x, so the entrance ticket is $18!
