range of 2|x|

Solution

range

2 ∣ x ∣

Solution

f (x) \geq 0

+1

Interval Notation

[0, \infty)

Solution steps

The range of an absolute function of the form

c ∣ a x + b ∣ + k

is

f (x) \geq k

k = 0

f (x) \geq 0

Popular Examples

inverse of f(x)=3x+4 inverse

f (x) = 3 x + 4

extreme f(x)=4x^2-8 extreme points

f (x) = 4 x^{2} - 8

line y= 1/2 x line

y = \frac{1}{2} x

inflection x^5-5x inflection points

x^{5} - 5 x

inverse of f(x)=100(1-t/(40))^2 inverse

f (x) = 100 (1 - \frac{t}{40})^{2}
