range of f(x)=2sqrt(2x+2)-4

range

f (x) = 2 2 x + 2 - 4

f (x) \geq - 4

Interval Notation

[- 4, \infty)

Solution steps

The range of an radical function of the form

c a x + b + k

f (x) \geq k

k = - 4

f (x) \geq - 4

f (x) = \frac{2 x - 2 x ^{3} + 3}{4 x ^{3} - x ^{2} - 4}

(5, - 3), (- 1, 3)

(- 6, 4), (- 5, - 4)

1 - x^{2}

f (x) = 4 x - 3 y = 174 x - 3 y = 17
