range of f(x)=2x^2-6x+5

Solution

range

f (x) = 2 x^{2} - 6 x + 5

Solution

f (x) \geq \frac{1}{2}

+1

Interval Notation

[\frac{1}{2}, \infty)

Solution steps

Vertex of

2 x^{2} - 6 x + 5 :

Minimum

(\frac{3}{2}, \frac{1}{2})

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}) = (\frac{3}{2}, \frac{1}{2})

f (x) \geq \frac{1}{2}
