It looks like you've uploaded an image containing a set of functions and some operations to perform. Let's break it down step by step to solve the given problems.

### Functions given:
- \( a(x) = x + 1 \)
- \( b(x) = x^2 - 1 \)
- \( c(x) = 2x + 3 \)
- \( d(x) = 3x - 5 \)
- \( e(x) = 3x^2 + 4 \)
- \( f(x) = 5x - 12 \)
- \( g(x) = \frac{x - 1}{8x + 5} \)
- \( h(x) = \frac{x^2 - 2x + 1}{x + 1} \)
- \( i(x) = \frac{x^2 - 1}{3x^2 + x - 5} \)

Now let's solve the listed questions:

### a. \( (a \cdot e)(x) \)
Multiply \( a(x) \) and \( e(x) \):
\[
a(x) \cdot e(x) = (x + 1)(3x^2 + 4)
\]
Expanding this:
\[
(x + 1)(3x^2 + 4) = x \cdot 3x^2 + x \cdot 4 + 1 \cdot 3x^2 + 1 \cdot 4 = 3x^3 + 4x + 3x^2 + 4
\]
Thus:
\[
(a \cdot e)(x) = 3x^3 + 3x^2 + 4x + 4
\]

### b. \( (c \cdot d)(-2) \)
First, compute \( c(-2) \) and \( d(-2) \):
\[
c(x) = 2x + 3 \quad \Rightarrow \quad c(-2) = 2(-2) + 3 = -4 + 3 = -1
\]
\[
d(x) = 3x - 5 \quad \Rightarrow \quad d(-2) = 3(-2) - 5 = -6 - 5 = -11
\]
Now, multiply:
\[
(c \cdot d)(-2) = -1 \cdot (-11) = 11
\]

### c. \( (c - d)(x) \)
Subtract \( d(x) \) from \( c(x) \):
\[
c(x) - d(x) = (2x + 3) - (3x - 5)
\]
Simplifying:
\[
c(x) - d(x) = 2x + 3 - 3x + 5 = -x + 8
\]
Thus:
\[
(c - d)(x) = -x + 8
\]

### d. \( (f' \cdot d')(x) \)
First, find the derivatives of \( f(x) \) and \( d(x) \):
\[
f(x) = 5x - 12 \quad \Rightarrow \quad f'(x) = 5
\]
\[
d(x) = 3x - 5 \quad \Rightarrow \quad d'(x) = 3
\]
Now multiply the derivatives:
\[
(f' \cdot d')(x) = 5 \cdot 3 = 15
\]

### e. \( (c \cdot e)(3) \)
First, compute \( c(3) \) and \( e(3) \):
\[
c(3) = 2(3) + 3 = 6 + 3 = 9
\]
\[
e(3) = 3(3^2) + 4 = 3(9) + 4 = 27 + 4 = 31
\]
Now multiply:
\[
(c \cdot e)(3) = 9 \cdot 31 = 279
\]
