The graph of y=2x2 + 10x +12 is shown. If the graph crosses the y axis at the point (0,k), what is the value of k?
Correct answer: D. 12
- A. 2
- B. 6
- C. 10
- D. 12
Explanation
To find where the graph crosses the y-axis, substitute x = 0 into y = 2x2 + 10x + 12. Simplifying gives y = 12, showing the intersection point as (0, 12). The correct answer is k = 12. Options 2, 6, and 10 are incorrect due to errors in substitution or calculation when x = 0 in the equation.
