Answer 1

Answer:

b=2

c=-24.01

Step-by-step explanation:

If I understood your question right you need to find the constants b and c in the polynomial:

$p(x)=x^2+bx+c$

such that:

$\lim_{x\to4} \frac{x^2+bx+c}{x-4}$

In order to get a system of two equations you can find limes when x goes to 4 from the right side or from the left side.

I solved this using a number that is close to 4. When it goes from right I used 4.1 and from left 3.9. This way you get two equations:

$16.81+4.1b+c=1\\15.21+3.9b+c=-1$

When you solve the system you get the answers above.
