If g(x)=x+1/x-2 and h(x) = 4 – x, what is the value of g(h(-3))?
Answered by maham237 @
g(h(-3)) = ⁸/₅ = 1.6
if g(x)=x+1/x-2 and h(x) = 4 – x, what is the value of g(h(-3))
In this problem we will find out the value of the function composition. There are two ways to do it.
Option 1
Step-1: compose (g o h)(x) = g(h(x))
Here h(x) as input into g(x). In other words, first we apply h(x), then apply g(x) to that result:
And we get,
Step-2: calculate the value of g(h(-3))
After getting g(h(x)) we proceed by calculating the value g(h(-3)).
And we obtain the final result:
Option 2
Step-1: count h(-3) initially
And we get,
Step-2: calculate the value of g(h(-3))
Here the value of h(-3), i.e. 7, as input into g(x).
Remember, f(7) as g(h(-3))
And we obtain the final result:
Keywords: if g(x) = x+1/x-2 and h(x) = 4 – x, what is the value of g(h(-3)), composition function, input, g(h(x)), value, initially, f(7), h(-3)
