STEP `: Recall what is a vertex form of a parabola

https://www.qalaxia.com/viewDiscussion?messageId=5d1433777ae99744ef6d360d

STEP 2: Plot the vertex

Compare y = -3(x-1)^{2} + 1 with the vertex form

y = a (x-h)^{2} + k

h = 1, k = 1

STEP 3: Plot the y-intercept

Recall what the y-intercept is

y-intercept is where the graph touches the x-axis. There is no x-value in the y-intercept.

So, plug in x= 0 in y = -3(x-1)^{2} + 1 to get y = -2

Plot (0,-2) on the y-axis

STEP 4: Join the points to graph a parabola
