Question

What is the domain and range of h(x)=x2−3x−4x−4?

Answer 1

Answer:

Step-by-step explanation:

h(x) = x^2 - 7x - 4

= (x - 7/2)^2 - 49/4 - 4

= ( x - 7/2)^2 - 65/4.

Domain of h(x) = R

Range of h(x) = [- 65/4 , + infinity)

Answer 2

Hello Friend..❤️❤️

Ans

-----

Given,

h(x) = X2 - 3X - 4X -4

=(X-7/2)^2-49/4-4

Domain = R

Range = _65/4 + infinity

Thank you
