If f(x)=x^2 and g(x)=2x+3, what is f(g(x))
IgorC [24]

Answer:

\huge\boxed{f(g(x)) = 4x^2 + 12x + 9}

Explanation:

In its raw form, function notation essentially represents an equation with only one unknown variable, expressed in terms of another.  Thus, f(x) = x² + 7x can be expressed as

g(x) = 2x + 3

f(g(x)) = (2x + 3)²

f(g(x)) = 4x² + 12x + 9

Hope it helps :) and let me know if you want me to elaborate.

Which statement is true about the relationship between entropy and spontaneity? O Spontaneous reactions tend to lead to higher e
dimulka [17.4K]

Answer:

The true statement is: Spontaneous reactions tend to lead to higher entropy.

Explanation:

The spontaneity of a reaction is linked to the value of Gibbs free energy (ΔG°). The more negative is this value, the more spontaneous is a reaction. At the same time, Gibbs free energy depends on enthalpy (ΔH°) and entropy (ΔS°), according to the following expression:

ΔG° = ΔH° - T.ΔS°

We can see that higher entropies (higher ΔS°) lead to more negative ΔG°, thus, more spontaneous reactions.
