Based on the function given, the domain of f(x) is -18 ≤ x ≤ 10 and the range is 16 ≤ f(x) ≤ 95
<h3>What are the domain and range?</h3>
The domain of a function is found by looking at a graph from left to right. This means that x will be equal to or greater than the smallest x value and less than or equal to the largest x value.
Domain is therefore:
-18 ≤ x ≤ 10
The range can be found by looking at the y value. The value if f(x) will be equal to or greater than the smallest y value and less than or equal to the largest y value.
Range is:
16 ≤ f(x) ≤ 95

Answer:
y = 0.5x + 2
Step-by-step explanation:
the y-intercept is 2, as shown in the graph
the slope is 0.5. this is because while the x-value goes up by 2, the y-value goes up by one (from 0, 2 to 2, 3).
using the slope formula of rise / run, you get 1/2, which is equal to 0.5
Answer:
5x+ 4
Step-by-step explanation:
First, put all of the x variables together. So 3x+4x=7x
7x + 4 -2x Since the 2x is negative you can subtract it from 7x and get 5x.
you can not add the four to the 5x because it does not have a matching variable.
So, you have: 5x+ 4
Answer:
92
Step-by-step explanation:
5x - 2y + (7x - y) = 5 * 7 - 2 * (-2) + (7 * 7 - (-2)) = 35 - (-4) + (49 + 4) = 39 + 53
= 92
