Answer:
The answer is C
Step-by-step explanation:
By using the quadratic formula, you get
a=1
b=5
c=7
so, when you substitute, you get:
-5±√5²-4(2)(7)
____________
2(1)
The next step is solving the square root and multiplying
G of f means plug f(x) into g(x)
but we want at x=2
we can solve to ways
1) find g(2)=7x-4
= 10
f(10)= 10 / (x-1)
answer is 10/ 9
method 2 is
(f(g)x)= 10/ ((7x-4)-1)
=10/(7x-5)
now x=2
=10/(7(2)-5)
=10/9
same answer, hope this helps
Answer:
d
Step-by-step explanation:
always d
I think you add subtract then find the domain and multiple it by the domain and add subtract and try to multiple it again
