Question

The graph of a quadratic function is given. Determine the function's equation.



A. j(x) = -x2 + 1

B. f(x) = -x2 - 2x - 1

C. h(x) = -x2 - 1

D. g(x) = -x2 + 2x + 1

Answer 1

@jigglypuff314 @jim_thompson5910 help me Please

Answer 2

Do you know what the parent graph y = x^2 looks like?
if you do, do you know how translations work?

Answer 3

no

Answer 4

i am not good in maths

Answer 5

hmm do you know what a quadratic equation is?

Answer 6

no again

Answer 7

@cwrw238 Is choice B correct

Answer 8

since the graph opens downwards the term in x^2 will be negative
and they all have that property
but the zeroes (where the graph cuts the x-axis are -1 and 1
so we can try
-(x - 1)(x + 1) = 0
-(x^2 - 1) = 0
-x^2 + 1 = 0
+1 is the maximum value ( see graph)

so the first option is correct
