Can someone help/explain to me the following problems that I'm about to post please. Thanks

OpenStudy (wintersuntime):

OpenStudy (triciaal):

a) in f(x) let x = 16 and in g(x) let x = 3 b) ordered pair is written as (x, y) y is f(x) when x = 16 and g(x) when x = 3

OpenStudy (wintersuntime):

okay

OpenStudy (triciaal):

c) did you notice that x and y are switched ?

OpenStudy (triciaal):

d) let x =25 in f(x) and compute

OpenStudy (wintersuntime):

for c why are they switched ?

OpenStudy (wintersuntime):

and for A I got \[f(16)=\sqrt{16-1} \]

OpenStudy (wintersuntime):

\[g(3)=3^2+7\]

OpenStudy (triciaal):

and also simplify g(x)

OpenStudy (wintersuntime):

but don''t we have to plug in 16 for f(X)

OpenStudy (triciaal):

yes and you did that correct but notice you have the radical sign over the 1 that was my intent to clearly show the difference

OpenStudy (wintersuntime):

oh okay
