Step-by-step explanation:
We need to show whether
or
so we'll do either one of them,
we'll convert f(x) to f^-1(x) and lets see if it looks like g(x).
we can also write it as:
now all we have to do is to make x the subject of the equation.
now we'll interchange the variables
this is the inverse of f(x)
and it does equal to g(x)
Hence, both functions are inverse of each other!
This can be shown graphically too:
we can see that both functions are reflections of each other about the line y=x.
The appropriate choice appears to be ...
B. -3/5
Using sinusoidal function concepts, it is found that the values are A = 2 and D = 2.
<h3>What is a sinusoidal function?</h3>The cosine function, with standard period, is represented by:
In which:
is the amplitude, which is the difference between the largest and smallest value.
- D is the vertical shift, considering that the standard cosine function has range between -A and A.
In this problem, the amplitude is of 4 - 0 = 4, hence:
The standard function has range between -2 and 2, in this problem it is between 0 and 4, hence the vertical shift up is of 2 units, that is, D = 2.
