f(x)=sqrt(x^2-81)

Solution

f (x) = x^{2} - 81

Solution

Domain : x \leq - 9 or x \geq 9

Range : f (x) \geq 0

X Intercepts : (9, 0), (- 9, 0)

Asymptotes : Slant y = x, y = - x

Extreme Points : Minimum (- 9, 0), Minimum (9, 0)

+1

Interval Notation

Domain : (- \infty, - 9] \cup [9, \infty)

Range : [0, \infty)

f(x)=x^3-x^2-5x-3

f (x) = x^{3} - x^{2} - 5 x - 3

f(x)=[cos(2x+1)]^3

f (x) = [cos (2 x + 1)]^{3}

f(x)=x(x-1),4<= x<= 8

f (x) = x (x - 1), 4 \leq x \leq 8

f(x)=sqrt(1+4x)

f (x) = 1 + 4 x

f(x)=e^{x^{1/2}}

f (x) = e^{x^{\frac{1}{2}}}
