Answer:
The value of g(2.7) is 31.49.
Step-by-step explanation:
Translations of a function:
Suppose that we have a function f(x).
The translation of f(x) a units to the left is given by g(x) = f(x+a).
The translation of f(x) a units to the right is given by g(x) = f(x-a).
The translation of f(x) a units up is given by g(x) = f(x) + a.
The translation of f(x) a units down is given by g(x) = f(x) - a.
Suppose the graph of f(x)=x^2 is translated 3 units right and 1 unit down.
Three units right:
[tex]g(x) = f(x+3) = (x+3)^2[/tex]
One unit down:
[tex]g(x) = f(x+3) - 1 = (x+3)^2 - 1[/tex]
What is the value of g(2.7)?
This is g when [tex]x = 2.7[/tex]. So
[tex]g(2.7) = (2.7+3)^2 - 1 = (5.7)^2 - 1 = 31.49[/tex]
The value of g(2.7) is 31.49.
