y=2x^2-x-1

Solution

y = 2 x^{2} - x - 1

Solution

Domain : - \infty < x < \infty

Range : f (x) \geq - \frac{9}{8}

X Intercepts : (1, 0), (- \frac{1}{2}, 0), Y Intercepts : (0, - 1)

Vertex : Minimum (\frac{1}{4}, - \frac{9}{8})

Inverse : \frac{1 + 8 x + 9}{4}, \frac{1 - 8 x + 9}{4}

y = lo g_{3} (x) + 2

f(x)=log_{13}(x)

f (x) = lo g_{13} (x)

y=((2-3x))/((7-x))

y = \frac{( 2 - 3 x )}{( 7 - x )}

periodicity of f(θ)=cos(θ/2)-cos((3θ)/2)periodicity

f (θ) = cos (\frac{θ}{2}) - cos (\frac{3 θ}{2})

f (x) = - x^{2} - 10
