The derivative of f(x) at x=3 is 2x=6 approaching from the left side (apply power rule to y=x^2). The derivative of f(x) at x=3 is m approaching from the right side. In order for the function to be differentiable, the limit of derivative at x=3 must be the same approaching from both sides, so m=6. Then, x^2=mx+b at x=3, plug in m=6, 9=18+b, so b=-9.
Answer:
{ y = 3x + 3
{ 3x - y = 3
B
(Just did the assignment 3/23/21)
(4/7)w = 12/7
w = (12/7) / (4/7)
w = 12/7 * 7/4
w = 84/28 = 3....it would take 3 weeks
Answer:
K>7
Step-by-step explanation:
If your looking for the answer, this question is invalid. However, if the question is asking for the function equation, the answer is y=3x-2
