Samantha thought of a number N, divided it by 5, and add 4. Then she told the result R to Kelly. Find the domain and range of this function.

The domain of the function is the input values for which the function exists. For the function above, the domain exists on all real values. Hence the domain of the function will be D =

The range of the function is the output values for which the function exists. For the function above, the range also exists on all real values. Hence the range of the function will be R =

The number N thought by Samantha divided by5 is expressed as;

If the result is added to 4 and stored as R, then;

This gives the required result

The domain of the function is the input values for which the function exists. For the function above, the domain exists on all real values. Hence the domain of the function will be D =

The range of the function is the output values for which the function exists. For the function above, the range also exists on all real values. Hence the range of the function will be R =

the answer is d

the answer is in the first quadrant, which make the y-int positive.

since the dots are going down, therefore the correlation is negative

i hope it is right.
