Question

Which expression is equal to f(x)=g(x)?

a) 712+911−2,646/71=1−14/x+21​
b) 712+911−2,646/71=1+14/x+21​
c) 712+911−2,646/71=1−14/x−21​
d) 712+911−2,646/71=1+14/x−21​

Answer 1

The expression that is equal to f(x)=g(x) is option d) 712+911−2,646/71=1+14/x−21​.

Step-by-step explanation:

The expression that is equal to f(x)=g(x) is option d) 712+911−2,646/71=1+14/x−21​.

To determine which expression is equal to f(x)=g(x), we need to simplify each of the options. Option a) has a subtraction where it should be addition and option c) has a negative sign in front of the second fraction, which is incorrect. Option d) is the correct expression since it has the correct addition and subtraction signs.

Therefore, the expression that is equal to f(x)=g(x) is option d) 712+911−2,646/71=1+14/x−21​.
