Answer:

Step-by-step explanation:
Notice that the red graph does not globally differ from the black graph: it would have been approximately the same one unless it had been displaced by 3 units up. Therefore, it was only the ordinate axis that underwent our change:
.
Answer:
840
Step-by-step explanation:
its 280 times 3 so you multiply
X = [-b + - sqrt(b^2 - 4 * a * c)] / 2a
x = [5 + - sqrt(25 - 4* 1 * -4)] /2
x = [5 + - sqrt(25 + 16)] /2
x = [5 + - sqrt(41)]2
x = [5 + sqrt(41)]/2 = 5.7
x = [5 - sqrt(41)] /2 = -0.7
The answer is -0.7
