The domain of a function is the set of all possible input values (often the "x" variable), which produce a valid output from a particular function; the set of all real numbers for which a function is mathematically defined.

1 Answer/Comment

2x^2 + 6x - 8 = 0

2(x - 1)(x + 4) = 0

x - 1 = 0 or x + 4 = 0

x = 1 or x = - 4

2(x - 1)(x + 4) = 0

x - 1 = 0 or x + 4 = 0

x = 1 or x = - 4

1 Answer/Comment

2 + 4x - 45 = 0

(4x) + (2 - 45) = 0

4x - 43 = 0

4x = 0 + 43

4x = 43

x = 43/4

(4x) + (2 - 45) = 0

4x - 43 = 0

4x = 0 + 43

4x = 43

x = 43/4
