34 is larger than 3, so 34.653
Is the last one
(-Infinity, -3] U (-1, positive infinity)
Ok
First factor out the first 2 terms as follows:-
y = 1/2(x^2 - 8x) + 21
Now complete the square on x^2 - 8x:-
y = 1/2[ (x - 4)^2 - 16] + 21
y = 1/2(x - 4)^2 - 8 + 21
y = 1/2(x - 4)^2 + 13 Answer
Answer:
π radians=180°(basic definition) 8π9 radians=89⋅180∘=160∘
