<span>2^2 times 2^-5 i think but i am not positive</span>
The answer is y = -3x + 11, if you plug in a few examples it works.
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.
Replace n with 12.
9 + 12 / 3 - 6
Simplify.
21 / -3 = -7
Hope this helps!
Y = 3x + 13
You can get this by using the same slope and then plugging into the equation to find the intercept. <span />
