<h2>
x= 0 and x= 1</h2>
Step-by-step explanation:
Given g(x) = x+2 and f(x) = 
If f(x) = g(x)
⇔
= x+2
⇔
Only x= 1 and x=0 will be satisfy the above equation.
If x= 1, it gives and x=0 gives

⇔2=2 ⇔1=1
Let x be the month on which the fee for two plans are equal.
Therefore,
150 + 10x = 50 + 30x
10x - 30x = 50 - 150
-20x = -100
x = 5
Cumulative cost = 150 + 10(5)
= 150 + 50
= 200
Hence, Karan will pay a cumulative cost of $200 dollars with either plan to go to the gym for 5 months.
