Question

Need help with this problem I have 2 choose which one of these is a linear function have to choose all that apply

Answer 1

Linear functions are the function which represents a straight line in graph.

A. y=2x-4

Here the graph drawn will be a straight line and thus it is a linear function.

B.

$y=-x^2+3$

Here the equation is quadratic and thus would represent a parabola. So the function is not linear.

C. The table here shows that the value of y first increases with increase in x reaches zero and again decreases with increase in x. Thus the graph wouldnot be a straight line and thus it doesnot give a linear function.

D. The tble here shows y increases linearly with increase in x.Thus it would give us a linear function.

E.The graph here is a straight line and thus it is a linear function.

F.The graph here is a parabola and thus is non linear.

Thus the linear function are

A,D,F
