f(x)=(x+5)(x-4)

Solution

f (x) = (x + 5) (x - 4)

Solution

Domain : - \infty < x < \infty

Range : f (x) \geq - \frac{81}{4}

X Intercepts : (- 5, 0), (4, 0), Y Intercepts : (0, - 20)

Vertex : Minimum (- \frac{1}{2}, - \frac{81}{4})

Inverse : \frac{- 1 + 4 x + 81}{2}, \frac{- 1 - 4 x + 81}{2}

f(d)=25d^2-80d^4+64

f (d) = 25 d^{2} - 80 d^{4} + 64

f (k) = k^{3} - 3 k + 1

f(n)=(1165409)/(2018n^{8160600)}

f (n) = \frac{1165409}{2018 n ^{8160600}}

f(x)=(sin(x))/((2-sin^2(x)))

f (x) = \frac{sin ( x )}{( 2 - sin ^{2} ( x ) )}

p(x)=(x^2+3x+1)*(x+4)

p (x) = (x^{2} + 3 x + 1) \cdot (x + 4)
