He graph of which function has an axis of symmetry at x = ? f(x) = 2x2 + x – 1 f(x) = 2x2 – x + 1 f(x) = x2 + 2x – 1 f(x) = x2 – 2x + 1

x intercept = (-1,0)   (4,0)

answer: 21$

step-by-step explanation:

$42 / $14 = 3   (ratio 3: 1)

$7 x 3 = $21

the equation for this situation is y=122+45. to solve the equation you would add 45 and 122 to get a total of 167lbs. in conclusion, grace's weight eight weeks ago was 167lbs.  

i think is g(1)=-1.

hope that i can
