Question

Range values y=3x+1 if the domain is -1,0,1,4​

Answer 1

Range = {-2, 1, 4, 13}

Explanation:

Domain is the set of x-values that are allowed for the function. The values for which the function is defined.

Range is the set of y-values that are allowed for the fucntion. The values for which the function is defined.

Since domain is given as:

Domain = {-1, 0, 1, 4}

We have to plug in each of the 4 values and find the corresponding 4 values for the range. Lets do this below:

y = 3x + 1

y = 3(-1) + 1

y = -2

y = 3x + 1

y = 3(0) + 1

y = 1

y = 3x + 1

y = 3(1) + 1

y = 4

y = 3x + 1

y = 3(4) + 1

y = 13

So, the range would be:

Range = {-2, 1, 4, 13}
