welshfella · Answer

one way to do this is to plug in each of the values of x given in the 4 choices and see which one fits

welshfella · Answer

note the sign ≥  means 'greater than OR equal to'

welshfella · Answer

so for the first one, x = 3
left side of the inequality = 42 - 5(3) + 3^2
right side   ....................   = 3^3 + 3^2

work these 2 out and see if they fit.
