Answer:
f(x) and g(x) are inverse functions
Step-by-step explanation:
In the two functions f(x) and g(x) if, f(g(x)) = g(f(x)) = x, then
f(x) and g(x) are inverse functions
Let us use this rule to solve the question
∵ f(x) = 3x²
∵ g(x) = 
→ Find f(g(x)) by substitute x in f(x) by g(x)
∴ f(g(x)) = 3()²
→ Cancel the square root with power 2
∴ f(g(x)) = 3(
)
→ Cancel the 3 up with the 3 down
∴ f(g(x)) = x
→ Find g(f(x)) by substitute x in g(x) by f(x)
∴ g(f(x)) = 
→ Cancel the 3 up with the 3 down
∴ g(f(x)) = 
→ Cancel the square root with power 2
∴ g(f(x)) = x
∵ f(g(x)) = g(f(x)) = x
→ By using the rule above
∴ f(x) and g(x) are inverse functions

Tip: If you’re not sure on answers for I-Ready, just turn off your WiFi, pick the answer you think is right and yeah! If you get it wrong, click “Next” and it’s gonna load load and then there’s gonna be a bar on the top and click that, then it’s gonna show you something to tell your teacher, after it said that, turn back on your WiFi and you’re still at the same spot! reply back if you didn’t understand since I am rushing.
Answer:
c
Step-by-step explanation:
Sure... a good example of that is when you have non-linear expressions in the system, like say for example a linear and a quadratic, like y = 4x and y = x².
recall that for a system of equations, where the graph of both equations intersect, is the solutions, check the picture below.
