I think it might be f^-1 (x) = x/2 - 3/2
I hope this helps!
Cos Z = 32/40 => Z= cos-¹(32/40) =>
sin Z = sin (cos-¹(32/40)) = 3/5
Answer:
Step-by-step explanation:
The greater the magnitude of the leading coefficient, the narrower the parabola.
Widest: f(x) = 0.5x²
Next: f(x) = -x²
Next: f(x) = 2x²
Narrowest: 3x²
