range of x^2-7x-30

Solution

range

Solution

f (x) \geq - \frac{169}{4}

+1

Interval Notation

Solution steps

Vertex of

x^{2} - 7 x - 30 :

Minimum

(\frac{7}{2}, - \frac{169}{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}) = (\frac{7}{2}, - \frac{169}{4})

f (x) \geq - \frac{169}{4}
