GCSE Secondary Maths Age 13-17 - Graphs: Graphs / Functions - Explained

What is the turning point of a graph?

• The point where the graph is horizontal

• The point where the graph changes direction

• The point where the graph ends

• The point where the graph starts

How do you determine the roots of a function from its graph?

• By measuring the distance between peaks

• By locating the turning point

• By identifying where the graph intersects the x-axis

• By finding where the graph is highest

What is the estimated negative root of the function F(x) from the graph?

• -0.5

• -0.72

• -1.0

• -0.9

What does F(1.5) represent in the context of the graph?

• The maximum value of the graph

• The x-coordinate of the turning point

• The y-coordinate when x is 1.5

• The slope of the graph at x = 1.5

What is the estimated value of F(1.5) from the graph?

• -2.5

• -3.0

• -2.8

• -3.2
