Question

.

Answer 1

x^2 is positive so it opens up
vertex is a minimum
you find x-intercepts by solving x^2 - 4x + 3 = 0
vertex is at - (-4) / 2 (x coordinate) - plug this into the function to get y coordinate
the graph is a curve called a parabola which is symmetrical about the vertical line passing through the vertex
