Answer:
A) f(x) = 2x + 3
B) f(x) = x - 5
C) f(x) = 2x + 4
Step-by-step explanation:
To find - Please write the function(x) from the given rules:
A) Twice the input value plus three.
B) The input value minus five.
C) To get the output, multiply the input by two, then add four.
Proof -
Let us assume that the input = x
The output = f(x)
Now,
A)
f(x) = 2x + 3
B)
f(x) = x - 5
C)
f(x) = 2x + 4
The domain of a function is the set of all acceptable input values (X-values). The range of a function is the set of all output values (Y-values).
ok so you need to pick out a point on the live. i did (10,5). now plug the y coordinate into the y in the equation and the x into the x in the equation. your equation is now 5=m x 10. now think, what multiplied by 10 equals 5? the answer is 0.5 or 1/2. so to show work, divide 5 by 10. 0.5 or 1/2 that is the answer to your problem.
