Answer:
f(x) = 3 - 4x^2
Step-by-step explanation:
Quadratic Equation form: f(x) = ax² + bx + c
Quadratic function has a x (variable) with and exponent of 2.
They also leave a curve line on a coordinate plane. As you can see on the picture. ↓
a^2 + b^2 = c^2
a = sqrt(c^2 - b^2) = sqrt (20^2 - 16^2)
= 12
sin = a/c = 12/20
= 3/5
cos = b/c = 16/20
= 4/5
tan = a/b = 12/16
= 3/4
csc = c/a = 20/12
= 5/3
= 1 2/3
sec = c/b = 20/16
= 5/4
= 1 1/4
