Answer:
f(x), h(x), g(x)
Step-by-step explanation:
For a quadratic in standard form, ...
ax² +bx +c
the axis of symmetry is ...
x = -b/(2a)
For the various functions, the axes of symmetry are ...
f(x): x = 0/(2·3) = 0
g(x): x = -(-4)/(2·1) = 2
h(x): x = (-4)/(2(-2)) = 1
From least to greatest axis of symmetry the functions are ...
f(x), h(x), g(x)
Answer:
Step-by-step explanation:
The trigonometric function that needs a domain restriction of to make it invertible is
.
The function will pass the horizontal line test on this interval therefore making it an invertible function on this interval.
This explains why the inverse tangent function, has range
.
