Answer 1

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
