So for this we have to find a number both can fit into. Let's list multiples of both numbers to find it.
8, 16, 24, 32, 40
12, 24, 36, 48
Looks like 24. The answer is 24.
Answer:
see explanation
Step-by-step explanation:
f(x) is valid for all real values of x , so
domain is x ∈ R
Since the coefficient of the x² term < 0 , then
f(x) has a maximum vertex at (0, 5 )
range is ( - ∞ , 5 ]
