Question

Pick one answer choice. Please help! I want to make sure i’m doing it right for practice test!

Answer 1

The product of the two functions is:

$(f \times g)(x) = 10x$

So the correct option is A.

Which one is the equivalent expression?

Remember that the square root has the property.

$\sqrt{a}*\sqrt{b} = \sqrt{a*b}$

Here we have:

$f(x) = \sqrt{2x} \\\\g(x) = \sqrt{50x}$

Then the product is:

$(f \times g)(x) = 10x = f(x)*g(x) = \sqrt{2x}*\sqrt{50x} = \sqrt{(2x)*(50x)} \\\\(f \times g)(x) = 10x = \sqrt{100x^2} = \sqrt{100}*\sqrt{x^2} = 10*x$

the correct option is A.
