WebThe discriminant of the quadratic equation x 2 − ( 5 − k) x + ( k + 2) = 0 is Δ = k 2 − 14 k + 17. We want Δ to be always positive, then the given equation will always have two distinct real roots. For this to happen, the discriminant of Δ must be negative. But, the discriminant of Δ is Δ ′ = ( − 14) 2 − 4.17 = 128 > 0 is positive. WebTherefore, the range of the function is all real numbers, or ℝ. ℝ . For the function g ( x , y ) g ( x , y ) to have a real value, the quantity under the square root must be nonnegative:
