Answer:
Step-by-step explanation:
Domain is the value for which the equation is real, here 4 - x^2 should be positive because it is in root.
4 - x^2 >= 0
x^2 =< 4
So -2 <= x <= 2
For the range of function
Function is maximum when x^2 is minimum (= 0 ). So max = 4
Function is minimum when x^2 is maximum (=4 because of the range of x above), SO min = 0
For part 2 put the value of x as -2
f(-2) = 0 (by solving)
3f(-2) + 1 = 1
