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
Jordan
Answer:
A. 1%
B. 80%
C. 0.8, 8/10
Step-by-step explanation:
A. There are 100 blocks so each block is 1/100 which is 1%
B. As you can see, there are 80 blocks shaded so that would be 80/100 which is 80%
C. You can represent a percent as a decimal or a fraction
