Answer:
34347
Step-by-step explanation:
Use the formula s=p(1+r/k)^kt
p=30000
r=7% (interest) 
k=1 (because of per annum) 
t= 2 (years)
Hence: 30000(1+0.07/1)^1(2) = 34347
 
        
             
        
        
        
Answer:
f(x)^-1 = x - 4
D: {x is all real numbers}
Step-by-step explanation:
change f(x) to y
switch x with y and vice versa
solve for y
 
        
             
        
        
        
Answer:
y = 3x^2-6x+3    one real solution  
y = -x^2 - 4x + 7     two real solution
y = -2x^2+9x-11       two complex solutions 
Step-by-step explanation:
b^2-4ac = 0   1 repeated real solution 
b^2-4ac > 0   2 distinct real solutions 
b^2-4ac < 0   2 complex solutions
