Question

The function f(x) = –x2 − 2x + 15 is shown on the graph. What are the domain and range of the function? The domain is all real numbers. The range is {y|y < 16}. The domain is all real numbers. The range is {y|y ≤ 16}. The domain is {x|–5 < x < 3}. The range is {y|y < 16}. The domain is {x|–5 ≤ x ≤ 3}. The range is {y|y ≤ 16}.

Answer:The domain is all real numbers. The range is {y|y ≤ 16}

Step-by-step explanation:we have

This is the equation of a vertical parabola open downward

The vertex is a maximum

Find the vertex of the quadratic equation

—–> equation in vertex form

The vertex is the point (-1,16)

therefore

The domain is the interval —-> (-∞,∞) All real numbers

The range is the interval —-> (-∞,16] All real numbers less than or equal to 16

Answer:The Answer Is B

Step-by-step explanation:domain is all real numbers. The range is {y|y ≤ 16}.
