Let x be his score on the last test so that to get an average of 90
His to average score at year end (4 terms), including the last is:
(92 +94 + 98 + x)/4 =90
(92 +94 + 98 + x) =4 x 90
x = - 274 + 360
x= 86

The parent function for quadratic equations is as followed:

where a and b represent vertical and horizontal stretches, respectively, h is the horizontal shift, and k is the vertical shift.
So going from

to

,
We are shifting 1 to the left and 6 up.
The horizontal shift is in the negative direction because in the equation, h=-1 because:
The answer is A.
