Question

`f(x) = 2( {x})^(2) + 5 √((x + 2)`the domain for f(x) is all real numbers greater then or equal to _____.

Answer 1

`f(x)=2x^2+5\sqrt[]{x+2}`

the domain for f(x) is all real numbers greater than or equal to -2.

Remember in the real number domain we can't have negative values inside the square root because they are not defined.
