A + b = 80 + 45 = 125
Therefore, C is your answer.
Answer:
g(f(x)) =1 - (12/(x^2-10x+25) +4
Step-by-step explanation:
f(x) = x-5
g(x) = x^2 – 12/ x^2 +4
g(x) = 1– 12/ x^2 +4
so we have:
g(f(x)) = 1 -12/(x-5)^2 +4
g(f(x)) =1 - (12/x^2-10x+25) +4
We have that
<span>f(x)=-x+0.5
g(x)=x</span>²+3x-4
f(x)=g(x)------------> -x+0.5=x²+3x-4-------------> x²+3x-4+x-0.5=0
x²+3x-4+x-0.5=0---------------> x²+4x-4.5=0
using a graph tool
see the attached figure
the solution are the points (-4.915,0) and (0.915,0)
If you graph it,the equation will have a real solution and the solution has to cross the x Axis
