Question

What is the relative maximum and minimum of the function?
f(x) = 2x2 + 28x - 8

A. Minimum Value: 7  Range y > 7 
B. Minimum Value: -106 Range y > -7 
C. Minimum Value: -106 Range y > -106  
D. Minimum Value: -7 Range y > -7

stationary point is x = -7
plug it back to the first function and you get y=-106. there's no maximum. 
(-7,-106)
