Question

Select the generic equation suggested by a graph showing a half-parabola.

a
y = kx

b
y = kx2

c
y = k(1/x)

Answer 1

b

Step-by-step explanation:

every parabola (and every half-parabola is a parabola in its nature) is a quadratic function.

that means it has to have a squared variable term.

so, of course, it can only be b : y = kx²
