Answer 1

Answer: B: (1-5x²)³, all real numbers

Step-by-step explanation:

The notation $f\circ g(x)$ is called function composition, which is where you pass one function in as the value of another function. In other words, $\( f\circ g(x)=f(g(x)) \)$.

Since we have the values for f(x) and g(x), let's plug them in.

$f(g(x))\\f(1-5x^2)\\(1-5x^2)^3$

Hence, the best answer choice is B, as all real numbers would work and it is the cube of 1 - 5x².
