Answer:
a =1 and a=4.
Step-by-step explanation:
The function is

If we want f(x) to be continuous the denominator needs to be different to 0, otherwise f(x) will be indeterminate.
Now, for a a positive real we have that
will annulate the denominator, i.e
. But, if a = 1 we have:

so, the value
won't annulate the denominator.
Now, for a = 4 we have:

so, the value
won't annulate the denominator.
In conclusion, for a=1 or a=1, the function will be continuos for all real numbers, since the denominator will never be 0.

Step-by-step explanation:
f(x) = 5x - 8
g(x) = 9 - 6x²
= (fog)(-3)
= f( g(3) )
= 5x - 8
= 5(9 - 6x²) - 8
= 5(9 - 6(-3)² ) - 8
= 5(9 - 54) - 8
= 5(-45) - 8
= -225 - 8
= -233
(fog)(-3) = -233
