Answer:
Step-by-step explanation:
The discriminant of ax^2+bx+c=0 is b^2-4ac, in this case
4^2-4(2)10
16-80
-64
Since -64<0 there are two imaginary (or ‘complex’) solutions.
Note: if d=0, there is one real solution. if d>0, there are two real solutions.

Answer:
The answer to your question is f⁻¹(x) =
Step-by-step explanation:
Function
f(x) = 2x + 3
Process
1.- Instead of f(x) write y
y = 2x + 3
2.- Interchange the variables
x = 2y + 3
3.- Solve for y
- Subtract 3 in both sides
x - 3 = 2y + 3 - 3
x - 3 = 2y
- Divide by 2
4.- Write f⁻¹(x) instead of y
f⁻¹(x) =
