Step-by-step explanation:
F(2a)=35
35=(2a)^2-1
35=4a^2-1
minus 35 from both sidse
0=4a^2-36
facor out 4
0=4(a^2-9)
factor differece of 2 perfect squares
0=4(a-3)(a+3)
set to zero
a-3=0
a=3
a+3=0
a=-3
a=-3 or 3
F of x basically means y. If x is hours, then f(2) means after two hours, so on. It’s set equal to twelve so that is the total number of bacteria. So after two hours, there is twelve bacteria.
