B. (0, +infinity)

When it is asked to know (b×a)(x), it is being asked to know what are the Y coordinates that are common in both graphs. When it a multiplication think of "and" - what are the Y that are on one graph and simultaneously on the other graph.
Design the graph of both functions on a calculator, or online, wherever. Then, look for when both functions have coordinates. All of them that are common to both graphs are the domain of (b×a)(x).

Step-by-step explanation:

use order of operations (parenthesis, exponents, multiplication/division, addition/subtraction)

first ill handle the two innermost parenthesis

(4 + 3(2 - 8))

(4 + 3(-6))

(4 - 18)

-14

now lets move on to the next parenthesis

( 3 - 5^2(-14))

(3 - 25( - 14)

( 3 + 350)

353

now onto the last part of the problem

8^2 + 7 (353)

64 + 2471

2535 :))

Answer:

$7^{\frac{1}{3} }$

Step-by-step explanation:

Using the rule of exponents

$\sqrt[n]{a^{m} }$ ⇔ $a^{\frac{m}{n} }$ , then

$\sqrt[6]{7^{2} }$ = $7^{\frac{2}{6} }$ = $7^{\frac{1}{3} }$
