Step 1
Given;
[tex]y=x^2-3x-10[/tex]
Required; To graph the function
Step 2
Graph the function.
[tex]\begin{gathered} We\text{ use the points} \\ (-2,0),(5,0),(0,-10),(1.5,-12.25) \end{gathered}[/tex]
The point at which the graph cut the y-axis is the y-intercept.
[tex]\begin{gathered} The\text{ y-intercept in \lparen x,y\rparen is; \lparen0,-10\rparen} \\ \end{gathered}[/tex]
The y-intercept occurs at y=-10
