A probability of 0.075 corresponds to a z-score of about
, i.e.
The answer is C. Circle
Hope this helps :)
Aos= -b/2a so plunin your numbers and you'll get the AOS so you can find the vertex
Step-by-step explanation:
First, replace f(x) with y . ...
Replace every x with a y and replace every y with an x .
Solve the equation from Step 2 for y . ...
Replace y with f−1(x) f − 1 ( x ) . ...
Verify your work by checking that (f∘f−1)(x)=x ( f ∘ f − 1 ) ( x ) = x and (f−1∘f)(x)=x ( f − 1 ∘ f ) ( x ) = x are both true.
