Answer:
a = 7
Step-by-step explanation:
The function given is defined at x=1 as ...
f(1) = 3·1² = 3
In order to make the limit from the left be 3, we must have ...
ax -4 = 3 . . . . for x=1
1a = 7 . . . . . . .add 4
The value of the constant "a" is 7.
Alan has two more than twice as many chocolates as does alice
Alan = 2Alice + 2 ----(1)
Alan has half as many chocolates as does nadia
Alan = 1/2 Nadia
so Nadia = 2Alan ----(2)
if Alice has 'a' number of chocolates
from (1)
Alan = 2a + 2 ----(3)
from (2) and (3)
Nadia = 2 (2a+2) = 4a+4 ----(4)
So Alan Alice and Nadia have
(2a+2) + a + (4a+4) = 7a+ 6 #
