So you cant have a decimal in your divisor which means the problem sill become 18215/7 if that helps

The positive integer is 6.
The consecutive integers are 6 and 7.
X=15
Just divide 5x by 5 and 75 by 5
F(x) = x^2 + 3 is a function.
domain of f(x) = x^2 + 3 is all real numbers.
range is all real numbers greater or equal to 3.
