Answer:
Substitution Property of Equality
Step-by-step explanation:
<u>The substitution property of equality</u> states that if x = y, then x can be substituted in for y in any equation, and y can be substituted for x in any equation.
In your case,
if x = 4 and y = 3x - 11, then by Substitution Property of Equality,
Do you see that when we change
f(x) = 7x - 5
to
f(2) = 7(2) - 5
we are simply saying to substitute in 2 for x? Well that is what we are doing:
f(2) = 7(2) - 5
f(2) = 14 - 5
f(2) = 9
Now we find g(4) the same way:
g(x) = 4(x)
g(4) = 4(4)
g(4) = 16
Now we find the difference of the two functions:
f(2) - g(4)
9 - 16
-7
So, the answer is B.
