Solution

range

f (x) = ∣ x ∣ - 4

Solution

f (x) \geq - 4

+1

Interval Notation

[- 4, \infty)

Solution steps

The range of an absolute function of the form

c ∣ a x + b ∣ + k

is

f (x) \geq k

k = - 4

f (x) \geq - 4

Popular Examples

monotone 9x^{(2)}-x^3-3 monotone intervals

9 x^{(2)} - x^{3} - 3

inverse of f(x)=((4x-1))/((2x+3))inverse

f (x) = \frac{( 4 x - 1 )}{( 2 x + 3 )}

inverse of (x-4)^3 inverse

(x - 4)^{3}

extreme 60x^2-20x^3 extreme points
