Hello tutor, please solve the problem in black circle (122). Please make sure you gave the absolute extrema for this problem. My professor says there is absolute extrema but I am unable to find it. I would leave a thumbs up and a good feedback. Thank you so much:)

For the following exercises, find the local and/or absolute maxima for the functions over the specified domain. 118. f(x) = x2+3 over [-1, 4] 119. y= x2 + 2 over [1, 4] 120. y = (x - x2)2 over [-1, 1] 121. y = over [0, 1] x - x2) 122. y = 19 - x over [1, 9]
