Provide an appropriate response. If the points in the table lie on a parabola, write the equation whose graph is the parabola. y = -3(x + 4)^2 - 5 y = 3x^2 + 24x - 43 y = -3(x + 4)^2 + 5 y = -3x^2 + 24x - 43
Solution
by verification
at x=7,y=-22
a) -22=3(7+4)2 -5
= 295 this is not correct
b) -22 = 3*72 +24*7-43
= 272 this is also not correct
c) -22 = -3(7+4)2 + 5
= -295 this also not correct
d) -22 = - 3*72 + 24*7 - 43
= -22 yes this is right answer
y = -3x2+24x - 43 is given parabola
