This is a method of substituting values into a given function. The value of the function f x is 7.6 is 3.8
<h3>Functions and values</h3>
Given the following function expressed as:
f(x) = 1/2(x)
We are to determine the value of f(7.6). Substitute x = 7.6 into the function as shown:
f(7.6) = 1/2(7.6)
f(7.6) = 7.6/2
f(7.6) = 3.8
Hence the value of the function f x is 7.6 is 3.8

Answer:
A graph that has an originality.(0,0) (this is the main thing. More below!!)
Step-by-step explanation:
- it might be positive or negative. it should also be linear.
- it also should not have a y-intercept.( the point where the line crosses the y axis)
- so for example a graph with an equation of y =3x or y=-3x is proportional. It has an originality since there is no y-intercept which is b in an equation. It also has a steady rate or slope of 3 which makes it linear.
Answer:
Distance traveled by Sierra in h hours at a rate of 2x miles per hour = 2xh
Explanation:
Distance traveled by a body = Velocity of the body * Time taken by the body
Here velocity of Sierra = 2x miles per hour
Time taken by Sierra = h hours.
Distance traveled by Sierra = 2x * h = 2xh
So distance traveled by Sierra in h hours at a rate of 2x miles per hour = 2xh
