Question

Write a function rule to find all odd numbers less than 10

a) f(x) = 2x + 1, where x < 10
b) f(x) = 2x, where x < 10
c) f(x) = x + 1, where x < 10
d) f(x) = x, where x < 10

Answer 1

The function rule f(x) = 2x + 1, where x < 10, can be used to find all odd numbers less than 10.

Step-by-step explanation:

To find all odd numbers less than 10, we can use the function rule f(x) = 2x + 1, where x < 10. This function rule will give us all the odd numbers less than 10.

Let's substitute values of x from 0 to 4 to find the corresponding odd numbers:

• f(0) = 2(0) + 1 = 1
• f(1) = 2(1) + 1 = 3
• f(2) = 2(2) + 1 = 5
• f(3) = 2(3) + 1 = 7
• f(4) = 2(4) + 1 = 9

So the odd numbers less than 10 using the function rule f(x) = 2x + 1 are 1, 3, 5, 7, and 9.
