Answer:
D
Step-by-step explanation:
substitute t=-3 in the equation
3(-3) squared +5(-3)+6=18
One way: log(A)-log(B) = log(A/B) right?
So, log( x^2-9/(x+3))
Now x^2-9 = (x+3)*(x-3), and x^2-9/(x+3) = x-3,
so log(x^2-9)-log(x+3) = log(x-3),
Indeed for all x but for x = -3, but probably no one asks you about that detail?
Answer:
So,
And,
But, given g(a) = 7
So, from 2nd and 3rd step,
3a-1=7
3a=6
Therefore, a = 2
