Math Problem Statement
Use the variable u for the inside function to express each of the following as a composite function. ( a) y = (8t ^ 2 - 5) ^ 2 NOTE: u(t) is the inside function and y(u) is the outside function. u(t) = y (u) = ( b ) P = 8e ^ (-0.5t) NOTE: u(t) is the inside function and P(u) is the outside function . u(t) =; P(u) = C 5 ( y^ 6 +7)
Solution
Let's break down each problem and express them as composite functions, using for the inside function and either or for the outside function.
(a)
Here, we want to express this equation as a composite function. The inside function is what is inside the outermost operation (in this case, the squaring operation).
-
Inside function : This will be the expression inside the square function.
-
Outside function : This represents the squaring operation applied to the inside function.
(b)
Here, the goal is again to express the equation as a composite function. The inside function is what is inside the exponential function.
-
Inside function : The exponent is the inside function.
-
Outside function : The outer function is the exponential operation multiplied by 8.
(c)
Here, we need to express the equation for as a composite function with as the inside function and as the outside function.
-
Inside function : This is the expression inside the function applied to 5.
-
Outside function : The outer function is multiplying by 5.
Summary:
-
(a)
-
(b)
-
