Answer:
E 8
Step-by-step explanation:
y = w x^2
If we double w and x, replae w with 2w and x with 2x and solve for y
y = (2w) * (2x)^2
Do the powers first
y = 2w * (4x^2)
y = 8wx^2
Y is now increased by a factor of 8
Y will be multiplied by 8.
Right option is (E)
We have, y = wx²
y is not 0.
If w and x are doubled
That means,
w' = 2w and x' = 2x
So , y' =w'x'²
or y' = (2w)×(2x)²
or y' = 2w×4x²
or y' = 8wx²
Since y = wx²
so y' = 8y.
That means if we double the w and x then y will be multiplied by 8.
