It's a quadratic with a positive x² coefficient, so a CUP, with a minimum

f(x) = 2x² -12 x + 13

= 2(x² - 6x) + 13

= 2(x - 3)² - 2(9) + 13

f(x) = 2(x - 3)² - 5

Since x-3 is always zero or positive the least value is

f(3) = -5

Answer: -5

3.25, 3.0, 2.75, 2.5, 2.25, ...
Morgarella [4.7K]
3.25 - 3 = 0.25
3 - 2.75 = 0.25
2.75 - 2.5 = 0.25
2.5 - 2.25 = 0.25

Since we subtracted those numbers, it means we are decreasing.
Therefore, the answer is decrease by 0.25.
