f(x) is read is function f of x.
Where x is the input variable and function f(x) gives output value of function for x input value.
For the given function, we have f(3).
If we compare f(3) by f(x), the x represented by input value 3.
Therefore, x value is 3 there.
And we also have f(x) =-5.
Because function value is -5. So we can read it as, "for x input value of the the function gives output value -5."
For the asked value of x is just x=3.
The vertex of the function f(x) = |x - a| is in (a, 0).
f(x) + a - shift the graph of function f(x) a units up.
Therefore:
The verex of y = |x + 5| is in (-5, 0).
The vertex of y + 7 = f(x) = |x + 5| + 7 is in (-5, 0 + 7) = (-5, 7).
The answer is 8% because each rate (2%) goes up $200, making $1200 at 6% into $1800 at 8%.
Hope this helps!
