Question

The graph of f(x) = x2 − 6x − 16 is shown. Which of the following describes all solutions for f(x)? a parabola passing through negative 2 comma zero, 0 comma negative 16, and 8 comma zero (−2, 0), (0, −16), (3, −25), (8, 0) (x, x2 − 6x − 16) for all real numbers (−2, 0), (8, 0) (x, y) for all real numbers

Answer 1

Let's find out zeros

• x²-6x-16=0
• x²-8x+2x-16=0
• (x-8)(x+2)=0
• x=8 or -2

x intercepts

• (8,0) U (-2,0)
