First, convert the given vertex and y-intercept into the vertex form of a quadratic function. Substitute the y-intercept to find 'a' in the** equation and reformulate the equation.** Finally, set the y-value of the equation to 0 and solve for x to get the x-intercepts. ;
The x-intercepts of the parabola with vertex (-1, -108) and y-intercept (0, -105) are (5, 0) and (-7, 0). To find these intercepts, we derived the equation of the parabola using vertex form and substituted the given points. We then set the equation to zero to solve for the x-intercepts.
