Question

A function is defined by f(x) = 3x+ 1 What is f(10)?

Answer 1

-------------------------------------------------------------------------------------------------------------

Answer: Option C, 31

-------------------------------------------------------------------------------------------------------------

Given: $\textsf{f(x) = 3x + 1}$

Find:  $\textsf{f(10)}$

Solution:  This can simply be done by inputting the value of 10 into all of the places where the variable x exists the in the expression and then simplifying the expression.

Plug in the values

• $\textsf{f(x) = 3x + 1}$

• $\textsf{f(10) = 3(10) + 1}$

Simplify the expression

• $\textsf{f(10) = 30 + 1}$

• $\textsf{f(10) = 31}$

After inputting the values and simplifying the expression we were able to determine that the best answer would be option C, 31.

Answer 2

Answer:

c) 31

Step-by-step explanation:

Given: f(x) = 3x + 1

We are being asked to find the function's value for x = 10.

Substitute 10 as the value of x in the function:

⇒ f(x) = 3x + 1

⇒ f(10) = 3(10) + 1

⇒ f(10) = 30 + 1

⇒ f(10) = 31

Therefore, the function's value at x = 10 is 31.
