Question

Find all real zeros of the function y=3x+1 a. 1/3 b.-1/3 c. 3, 1 d. 3

Answer 1

The zeroes of the function are:
`(-1)/(3)`.

Option b would be the correct answer.

Explanation:

The zeros of a function are defined as the point at which the value of the function is zero. We can say the zeros are the x values where the graph intersects the x-axis. We obtain these algebraically by setting the function equal to zero then solving.

Given

`y=3x+1`

Lets find all real zeros of the function.

Replace
`y` with 0.

`0=3x+1`

Subtract 1 from both sides of the equation

`-1=3x`

Divide both sides of the equation by 3.

`(-1)/(3) =(3x)/(3)`

Simplify the right side by cancelling the common factor of 3.

`(-1)/(3) =x`
