Question

1. Consider ihe following functions:

Answer 1

Answer:

Step-by-step explanation:

1) f(x) =0   : x² +9 =0    means  x² = -9      ..no solutions in R

2)g(x) =0 : (x-9)² =0   means  x-9= 0    ..... single solution : 9

3) h(x)=0 : (x+1)² - 9 = 0 means (x+1)² = 3²   so x+1=3 or x+1 = -3

two solutions : 2 and -4
