Solution

range

f (x) = - 3 ∣ x ∣

Solution

f (x) \leq 0

+1

Interval Notation

(- \infty, 0]

Solution steps

The range of an absolute function of the form

- c ∣ a x + b ∣ + k

is

f (x) \leq k

k = 0

f (x) \leq 0

Popular Examples

inverse of y=x^2-5x+6 inverse

y = x^{2} - 5 x + 6

extreme f(x)=5x^3-3x^5 extreme points

f (x) = 5 x^{3} - 3 x^{5}

intercepts of f(x)=x^2+20x+100 intercepts

f (x) = x^{2} + 20 x + 100

critical f(x)=x^2-6x+8 critical points

f (x) = x^{2} - 6 x + 8

symmetry x^2+8x+10 symmetry

x^{2} + 8 x + 10
