Graphing Quadratic: Standard Form

What piece of information does c identify in the following equation?
y=ax²+bx+c

• Zeroes

• Axis of Symmetry

• Direction

• y-intercept

Answer explanation

In the equation y=ax²+bx+c, the term 'c' represents the y-intercept. This is the value of y when x is 0, indicating where the graph intersects the y-axis.

What is the vertex of the graph shown above?

• (7,6)

• (-1,2)

• (2,-1)

• (5,0)

Is the vertex in this graph a max or min?

• Minimum

• Maximum
