Answer:
Transitive property
But it looks like substitution.
Step-by-step explanation:
F(g(x))
sub g(x) for every x in f(x)
f(g(x))=2(g(x))-4
f(x^2)=2(x²)-4
f(g(x))=2x²-4
Answer:
28% of 82
Step-by-step explanation:
25% of 90 is 22.5
28% of 82 is 22.96
You haven't supplied the "output value."
Supposing that the "output value" were 15, then F(x) = x + 7 = 15, and x = 8.
