Answer:
Let x be the value of the house before increase
Since it's increases add 7% to the overall 100%
107/100x = 749000
x = 700000
The value of the house before increase is £700000.
Hope this helps.
The value of F(3) = 27.
Step-by-step explanation:
Step 1:
F(x) is dependent on the value of x.
So x is independent while F(x) is dependent on x i.e. the value of F(x) depends on the value of x.
Step 2:
F(x) =
, if we have the x's value we can calculate the F(x)'s value.
Here the value of x is given as 3 so F(x) when x equals 3 can be calculated.

So F(3) = 27.
