m = 1.6
i can do 23 i can say
anything in ( ) first so its18= 11m and divide 11 by 11 its 0 so its stays m
m=18 what you do one side you do the other so 18 divided by 11
if the eqn of the parabola is f(x) = (x-4)(x+2), we need to mult. this out to find the coordinates of the vertex.
then f(x) = x^2 + 2x - 4x - 8, and f(x) = x^2 - 2x - 8.
one way in which you can find the vertex is to calculate x = -b / (2a). here, that comes to
x = = 1. f(1) = 1^2 - 2(1) - 8 = - 9. vertex is at (1, -9).
find another point on the curve: let x=0, for which y=-8. then (0, -8) is on the curve. plot the vertex and this point and draw a smooth parabola thru both.
the last table is proportional
simplify the last table and you will find that y is 1/2 of x and its constant.
and i hope it c:
have a nice day
25.10y(7) how do do this...
