Step-by-step explanation:
Given
Solving (a): Expression for V(x)
We have:
Substitute known values
Solving (b): Simplify V(x)
We have:
Solve the expression in bracket
Factor out x
Express as difference of two squares
Cancel out x - 3
Solving (c): V(50), V(100), V(1000)
Substitute 50 for x
Substitute 100 for x
Substitute 1000 for x
Solving (d): V(x) = 3000, find x
Cross multiply
Equate to 0
Open brackets
Collect like terms
Solve using graphs (see attachment)
