Question

will give medals to first one who gets it!
Sketch the following graphs:


a. y = x2


b. y = 2x2


c. y = .50x^2





Describe how the coefficients of x2 affect the graphs.



a.

the smaller the coefficient of x2, the narrower the graph

c.

the coefficient of x2 defines if the line is a parabola, a V shaped graph or a straight line graph


b.

the larger the coefficient of x2, the narrower the graph

Answer 1

a. negative coefficient makes it a bell jar with a max y value and a positive make is U shaped with min y value.
b. graph transformation state that if a f(x) is squeezed/reduced along parallel to the x-axis, f(x) is multiplied by a number meaning smaller obtaining f(nx) where n is a constant., thus answer is c
