Question

What function does this graph represent?
A.
f(x) = -0.2(x − 2)^2 + 1
B.
f(x) = 0.2(x − 2)^2 + 1
C.
f(x) = -0.2(x − 2)^2 − 1
D.
f(x) = 0.2(x − 2)^2 − 1

Answer 1

any idea?

Answer 2

no idea

Answer 3

it is an upward parabola.
so option B or D.
to find y -intercept
put x=0 in B.
\[y=0.2(0-2)^2+1\]
so y=0.8+1=1.08
which is true.
so B is the option.
