5. compare the parent function f(x) = x 2 to the quadratic function f(x) = –2x 2 – 6. the 6 in the function does which of the following? (1 point)
it makes the graph narrower than the parent function.
it makes the graph wider than the parent function.
it causes the graph to reflect across the x axis and open downward.
it shifts the vertex of the graph vertically.

For each expression use a property to write an equivalent expression.

The data in the table represent the height of an object over time. which model best represents the data? height of an object time (seconds) height (feet) 05 1 50 2 70 3 48 quadratic, because the height of the object increases or decreases with a multiplicative rate of change quadratic, because the height increases and then decreases exponential, because the height of the object increases or decreases with a multiplicative rate of change exponential, because the height increases and then decreases
