range of x^2+1

Solution

range

x^{2} + 1

Solution

f (x) \geq 1

+1

Interval Notation

[1, \infty)

Solution steps

Vertex of

x^{2} + 1 :

Minimum

(0, 1)

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, 1)

f (x) \geq 1

Popular Examples

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

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

inverse of f(x)=2sqrt(x-3)-5 inverse

f (x) = 2 x - 3 - 5

midpoint (-2,10),(1,-6)midpoint

(- 2, 10), (1, - 6)

domain of f(x)=6(x+7)-5 domain

f (x) = 6 (x + 7) - 5

domain of y=x^3-2 domain

y = x^{3} - 2
