Chapter 5: Q 9. (page 256)

Evaluate each expression using the graphs of $y = f (x)$ and $y = g (x)$ shown in the figure.
(a) $(g 鈭� f) (- 1)$ (b) $(g 鈭� f) (0)$ (c) $(f 鈭� g) (- 1)$ (d) $(f 鈭� g) (4)$ .

Short Answer

Expert verified

The value of the function is :

(a) 4 (b) 5 (c) 7 (d) -2.

Step by step solution

Step 1. Given Information.

The graphs of $y = f (x)$ and $y = g (x)$ .

Step 2. Evaluation of functional value.

The functional value

(a) $g (f (- 1)) = g (1) = 4$ .

(b) $g (f (0)) = g (0) = 5$ .

(d) $f (g (2)) = f (2) = - 2$ .

Begin with the graph of $y = e^{x}$ and use transformation to graph the function. Determine the domain, range and horizontal asymptote of the function.

$f (x) = e^{x} - 1$

solve each equation

$9^{2 x} 27^{x^{2}} = 3^{- 1}$

A function $f$ has an inverse function. If the graph of $f$ lies in quadrant II, in which quadrant does the graph of $f^{- 1}$ lie?

In Problems 61鈥�72, the function f is one-to-one. Find its inverse and check your answer.

$f (x) = \frac{3 x + 4}{2 x - 3}$

In Problems $33 - 40$ , the graph of an exponential function is given. Match each graph to one of the following functions.
