Can someone explain to me how to solve it?
1 answer:
Step-by-step explanation:
The problem is basically asking for the roots, or the x-intercepts. To do this, follow the quadratic formula:
b is the second coefficient(+13)
a is the first coefficient(5)
c is the third coefficient(-6)
When the formula is negative, it just means to flip the sign from a positive to negative or negative to positive. Plug in and simplify.

Answer:
x = 8
Step-by-step explanation:
f(x) =
g(x) =
(f o g)(x) = f[g(x)]
=
This function is defined for (x + 3) > 0
(x + 3) - 3 > 0 - 3
x > -3
From the given options x = 8 is the only solution which is greater than -3.
Therefore, x - 8 is in the domain of the given function.
