Math Problem Statement

Complete the function table for f(x) = x + 3, where the table contains values for x as -4, -3, 0, 4, and 5.

Solution

The given function f(x)=x+3f(x) = x + 3 defines the rule to compute the values of f(x)f(x) for any xx. Let's calculate the missing values in the function table:

Function Table Calculation:

  1. When x=4x = -4: f(4)=4+3=1f(-4) = -4 + 3 = -1

  2. When x=3x = -3: f(3)=3+3=0f(-3) = -3 + 3 = 0

  3. When x=0x = 0: f(0)=0+3=3f(0) = 0 + 3 = 3

  4. When x=4x = 4: f(4)=4+3=7f(4) = 4 + 3 = 7

  5. When x=5x = 5: f(5)=5+3=8f(5) = 5 + 3 = 8

Completed Table:

\hline x & f(x) \\ \hline -4 & -1 \\ -3 & 0 \\ 0 & 3 \\ 4 & 7 \\ 5 & 8 \\ \hline \end{array}$$ Let me know if you'd like a detailed explanation of each step or have more questions! --- ### 5 Related Questions: 1. What is the general procedure for evaluating a linear function like $$f(x) = x + 3$$? 2. How can you tell if a given function is linear by looking at its table or rule? 3. If the function were $$f(x) = 2x + 1$$, how would the table change? 4. What does the graph of $$f(x) = x + 3$$ look like? 5. How can you calculate $$f(x)$$ if the input $$x$$ is a fraction or decimal? ### Tip: Always substitute $$x$$ into the function rule carefully and perform arithmetic step-by-step to avoid errors.
