range of-2x^2+12x-14

Solution

range

- 2 x^{2} + 12 x - 14

Solution

f (x) \leq 4

+1

Interval Notation

(- \infty, 4]

Solution steps

Vertex of

- 2 x^{2} + 12 x - 14 :

Maximum

(3, 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 = - 2,

Vertex

(x_{v}, y_{v}) = (3, 4)

f (x) \leq 4

Popular Examples

inverse of f(x)=2-6x inverse

f (x) = 2 - 6 x

domain of f(x)=sqrt(7-x^2)domain

f (x) = 7 - x^{2}

range of (x^3-5)/(12)range

\frac{x ^{3} - 5}{12}

monotone x^3 monotone intervals

x^{3}

intercepts of f(x)=x^2+2x+1 intercepts

f (x) = x^{2} + 2 x + 1
