Question

Transcribed Image Text:**Question 15:**
The quadratic equation \( y = -2x^2 - 4x + 6 \) is graphed below.
**Graph Description:**
The graph displays a downward-opening parabola representing the quadratic equation \( y = -2x^2 - 4x + 6 \). It is plotted on a Cartesian plane with both x and y axes ranging from -10 to 10. The vertex of the parabola appears to be at approximately (-1, 8). The parabola crosses the y-axis at (0, 6) and has x-intercepts (roots) near x = -3 and x ≈ 1.
**Question:**
What is the value of the positive zero of the related function \( f(x) = -2x^2 - 4x + 6 \)?
