Math Problem Statement
Given f(x) = 2x^2 + 5x + 3, at what point does the graph intersect the y-axis?
Solution
The problem is asking where the graph of the function intersects the -axis.
To find where a graph intersects the -axis, we substitute into the equation of the function, since the -axis corresponds to .
Given: Substitute : Thus, the point where the function intersects the -axis is .
The correct answer is .
