Select the function that’s represented in the graph

a.) f(x)=x^2-3
b.) f(x)=-1/2x^2-3
c.) f(x)=-x^2-3
d.) f(x)=1/2x^2-3

answer:   x = 3 + √11     and     x = 3 - √11

step-by-step explanation:

x² - 6x + 9 = 11

(x - 3)² = 11

x - 3 = ±√11

    x = 3 ± √11

x = 3 + √11     and     x = 3 - √11

dont't really have enough info here but its likely

sss for the three sides being congruent ( its stands for side side side)

or

sas   for side angle side.   so a side is congruent and and angle and a side
