What's the y-intercept of y = 3x²- 6x + 4

• (4,0)

• (-4,0)

• (0,-4)

• (0,4)

Name the vertex to the given quadratic graph

• (2,3)

• (3,2)

• (0,-1)

• (4,-1)

Define Vertex

• Where the parabola touches or intersects the x-axis

• The highest or lowest point on the graph

• Where parabola line touches or intersects the x- axis, also called the x-intercept

• A line that divides the graph into two equal parts. i.e. cuts the graph in half

When given two functions and asked what are the solutions you are finding what?

• The maximum point.

• The point(s) at which the 2 lines intersect.

• Where is crosses the x-axis

• The minimum

When asked to find the zeros of a function, what are you finding?

• The x-intercepts.

• The roots.

• The y-intercept

• The highest point.

What is another name for the x-intercepts of a quadratic?

• y-intercept

• Zeros

• x-axis

• They don't have another name

Which is a zero of the graph?

• 0

• -1

• 1.5

• -3

Does the quadratic have a max/min vertex, and does the graph open up/down?

• max/ opens down

• min/ opens up

• max/ opens up

• min/ opens down

Does this graph have a maximum or minimum value?

• maximum

• minimum

• neither

• both

Determine the interval in which this function is INCREASING.
