1.2 ten thousands
is my opinion
F(x) > g(x)
2^x + 3 > 50x + 5
for x = 3 , f(3) > g(3)
11 > 155 (false)
for x = 10 , f(10) > g(10)
1027 > 505 (true)
for x = 9 , f(9) > g(9)
515 > 455 (true)
for x = 8 , f(8) > g(8)
259 > 405 (false)
the smallest,positive integer value of x is 9 since the value of 9 is the last number to exceeds g(x)
Y = total cost
40 = The one time fee
90 = the service charge per month
x = number of months
The answer is b because there is a negative in the exponent and the number needs to be a single digit and 54 is double digit. hope this helps!
