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:
Step-by-step explanation:
the quotient of is the result of dividing two terms
The first term is - Twice a number t: 2t
The second term is - and 12: 12 2t÷12or 2t12
