Determine f(-1); f(0) and f(2)
Solving f(-1)
In this case, we simply take x as;

Substitute -1 for x in 

Apply law of indices


Solving f(0)
In this case, we simply take x as;

Substitute 0 for x in

Answer:
x=20
Step-by-step explanation:
Vertical angles are equal
6x+10 = 5x+30
Subtract 5x from each side
6x-5x+10 = 5x-5x+30
x+10 = 30
Subtract 10 from each side
x+10-10 = 30-10
x =20
