Step-by-step explanation:$30 per month, $0.20 per text
A: 50 text messages in order for both plans to cost the same
Answer:
2
Step-by-step explanation:
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.
