range of-x^2-4

Solution

range

- x^{2} - 4

Solution

f (x) \leq - 4

+1

Interval Notation

(- \infty, - 4]

Solution steps

Vertex of

- x^{2} - 4 :

Maximum

(0, - 4)

For a parabola

a x^{2} + b x + c

with Vertex

(x_{v}, y_{v})

If

a < 0

the range is

f (x) \leq y_{v}

If

a > 0

the range is

f (x) \geq y_{v}

a = - 1,

Vertex

(x_{v}, y_{v}) = (0, - 4)

f (x) \leq - 4

domain of y=(x-1)/2 domain

y = \frac{x - 1}{2}

inverse of f(x)=3^x-9 inverse

f (x) = 3^{x} - 9

parallel y=x-3,(3,-2)parallel

y = x - 3, (3, - 2)

range of f(x)=x^3-x range

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