To multiply these expression, multiply the numeric parts, and sum the exponents of the literal parts (because the variable is the same: we're using the power property $a^b\cdot a^c = a^{b+c}$ ).

So, you have:

$3z^7 \cdot (4z^2) = 3\cdot 4 \cdot z^{7+2} = 12z^9$
$6a^5 \cdot (6a^5) = 6\cdot 6 \cdot z^{5+5} = 36z^{10}$
$6b^4 \cdot (-3b^4) = 6\cdot (-3) \cdot b^{4+4} = -18b^8$
$5x^4 \cdot (4x^2) = 5\cdot 4 \cdot x^{4+2} = 20x^6$

Answer:

Easy way to distinguish:

Linear function forms a AP and exponential function forms a GP

We see f(x) is series of:

8, 14, 20, 26, 32

This is a AP with common difference of 6 and the first term of 8

g(x) is series of:

4, 12, 36, 108, 324
This is a GP with common ratio of 3 and the first term of 4

1. g(x) is exponential function:

g(x) =4*3ˣ

2. f(x) is linear function:

f(x) = 6x + 8
