We are given four functions: $f(x)$ is represented graphically, $g(x)$ is given as a set of ordered pairs, $h(x) = -x + 1$, and $p(t)$ is given in a table. We need to evaluate the following composite functions: $f(g(-4))$ $g(h(2))$ $p(f(-1))$ $g(p(-2))$

1. Problem Description

We are given four functions: f(x)f(x) is represented graphically, g(x)g(x) is given as a set of ordered pairs, h(x)=x+1h(x) = -x + 1, and p(t)p(t) is given in a table. We need to evaluate the following composite functions:
f(g(4))f(g(-4))
g(h(2))g(h(2))
p(f(1))p(f(-1))
g(p(2))g(p(-2))

2. Solution Steps

First, we find g(4)g(-4). From the definition of g(x)g(x), we see that g(4)=1g(-4) = -1.
Then f(g(4))=f(1)f(g(-4)) = f(-1). From the graph of f(x)f(x), we have f(1)=5f(-1) = 5.
Next, we find h(2)h(2). We have h(x)=x+1h(x) = -x + 1, so h(2)=2+1=1h(2) = -2 + 1 = -1.
Then g(h(2))=g(1)g(h(2)) = g(-1). From the definition of g(x)g(x), we see that g(1)=3g(-1) = -3.
Next, we find f(1)f(-1). From the graph of f(x)f(x), we have f(1)=5f(-1) = 5.
Then p(f(1))=p(5)p(f(-1)) = p(5). From the table of p(t)p(t), we have p(5)=0p(5) = 0.
Finally, we find p(2)p(-2). From the table of p(t)p(t), we have p(2)=3p(-2) = 3.
Then g(p(2))=g(3)g(p(-2)) = g(3). From the definition of g(x)g(x), we see that g(3)=2g(3) = 2.

3. Final Answer

f(g(4))=5f(g(-4)) = 5
g(h(2))=3g(h(2)) = -3
p(f(1))=0p(f(-1)) = 0
g(p(2))=2g(p(-2)) = 2
