On a particular problem,

5. Given the function: y= (x + 1)^2 - 8

i) Identify each function is a linear, quadratic, sqrt, or reciprocal function. I got quadratic.

ii) State the domain and range. D = { x E R } R = { y E R | y ≥ -8}

iii) Determine f(3). Solved and got f(3) = 8

However on the last part.. I think it might be to vague or I may be dumb.. it states.

iv) Express the function in two other ways..

Umm, does that mean in graph form, ordered pairs, table of values? Im not quite sure I follow any help would be appreciated. Thanks in advance.
