Given h(x) = a⋅x²

If g(x) = 3x² and h(x) is wider than g(x), what could be the value of a?

• -4

• 4

• -3

• 2

Given f(x) = ax² , if 0 < a < 1 , the graph will transform by

• becoming wider or vertically compressed

• becoming narrower or vertically stretched

f(x) is transformed so that it maps onto g(x). Which equation would correctly represent g(x) in terms of f(x)?

• g(x) = f(x + 3)

• g(x) = f(x - 3)

• g(x) = f(x) + 3

• g(x) = f(x) - 2

Which equation best represents the graph?

• y = 2(x - 4)² + 5

• y = 2(x + 4)² + 5

• y = -2(x - 4)² + 5

• y = -2(x + 4)² + 5
