Write a Function rule for the table.

f(x) = x + 3
when x = 0, f(x) = 3
when x = 1, f(x) = 1 + 3 = 4
when x = 2, f(x) = 2 + 3 = 5
when x = 3, f(x) = 3 + 3 = 6
answer is D
f(x) = x + 3
Answer:
D. [tex]f(x)=x+3[/tex]
Step-by-step explanation:
We have been given a table of values. We are asked to write a function rule for our given table.
We can see from our given table that [tex]f(0)=3[/tex]. This means that the y-intercept of our given function is 3.
We can see that with each increase in x, the value of [tex]f(x)[/tex] increases by 1.
[tex]f(1)=4[/tex]
[tex]f(2)=5[/tex]
[tex]5-4=1[/tex]
This means slope of our given function is 1.
Upon substituting [tex]m=1[/tex] and [tex]b=3[/tex] in slope intercept form of equation, we will get:
[tex]y=mx+b[/tex]
[tex]f(x)=x+3[/tex]
Therefore, our required function is [tex]f(x)=x+3[/tex] and option D is the correct choice.
