Answer:
Step-by-step explanation:
Question 1:
We are some information, which is a table. The question is when we put in 3 what will we get out?
- We can look at the table. Let us look at the "x" side and find 3
- Go over to the next box (to the right) and we can see a 7. This 7 is the outcome or the result of when f(3).
So the answer is 7.
Question 2:
A table is provided, what is the outcome when -5 is placed into the function?
- by looking at the table and locating the -5 of the x-value, we can see that the outcome is -15.
Question 3:
Instead of a table, we are given a graph! And it is asking us, what is the output when we place -6 into the function?
- Let's us look at the graph
- We know that when we say input, we mean the x value. So by looking at the x-axis and -6, we should look what is the result.
- The graph is staying in the 1st and 2nd quadrant of the graph. What we can do is trace our finger or follow along and see where the graph lies when x = -6
- It looks like when x= -6, the output of the function is -6 also.
Question 4:
Instead of a table and graph, we are given a function! We are given f(x)= x-10 and the question is what is f(-7)?
- when the x in f(x) is replaced with a number, it is saying what is the input when this number goes into the function. So... replace "x" with -7.
f(x) = x-10
f(x) = (-7) -10
f(x) = -17
Question 5:
Again, we are given an function! The function is f(x) = 3x+4 and the question is what is f(8)?
f(x) = 3x+4
- replace "x" of the function with 8
f(8) = 3(8) +4
- now we need to solve the right side of the equation to get the output
f(8) = 24+4
f(8) = 28
