1) State the domain and range of each of the following functions:

a)y= 3x+ 4

b) y = $\displaystyle 3(x-4)^2 +5 $

c) y = √ 2x-10

(the root is over all the numbers for c)

d) y = √ $\displaystyle -x^2 + 4$

(the square root sign is over all the numbers for d) as well

e)y= 2 |1−x |−17

f) $\displaystyle y = x/ (x^2-x-6)$

Can someone help me find these plus explain why for d) e) and f)
