Question 1
Which one is NOT a linear function?
- Response: 2x² − 6 = 11
This equation is quadratic because it involves \(x\) raised to the power of 2, making it non-linear.
Question 2
The area, A, of an isosceles right triangle is a function of the length of its legs, s, and is represented by the equation A = ½ S² Is this function linear or non-linear?
- Response: non-linear
This is because the variable \(S\) is squared, which means the relationship is not linear.
Question 3
Which graph is NOT a function?
- Response: (The correct answer would depend on the graphs provided)
To determine which graph is not a function, you would look for any vertical line that intersects the graph at more than one point, which would violate the vertical line test for functions.
Question 4
Is this a linear function?
- Response: (The answer would depend on the equation provided in the quiz image)
If the equation is in the form of \(y = mx + b\), it is linear. If it involves variables that are squared or multiplied together, it is not.
Question 5
Is this a linear function?
- Response: (The answer would depend on the equation provided in the quiz image)
Again, if the equation is in the form of \(y = mx + b\), it is linear, while any more complex relationships would be non-linear.
