The quadratic has one root with multiplicity 2 if the discriminant is 0, which is

(That is, for a quadratic
, the discriminant is
.)
Set the discriminant equal to 0 and solve for
:





<span>STEP 1: Stick a "y" in for the "f(x)" guy:STEP 2: Switch the x and y. ( because every (x, y) has a (y, x) partner! ):STEP 3: Solve for y:<span>STEP 4: Stick in the inverse notation, continue. 1 2 3.
these are the steps and that is not correct </span></span>
Answer:
1,718.28
Step-by-step explanation:
1,548, percentage increased by 11% (percent) of its value = 1,718.28
