How do you find the intercepts and vertex for # y=-2|5x+8|+4#?
Vertex: (0, -12)
At x = 0, y = -12. The absolute value function just means that the graph will be symmetric about some point, forming a “V” shape in the case of a linear equation. The x intercepts are:
The vertex must be the point midway between these two for the linear symmetry. That will be the point at x = 0, where we have already found y to be -12.
