Find the value of k if f x kx+1
WebJan 8, 2024 · Using synthetic division, we see the remainder from division by (x-1) is 3-k. In order for (x-1) to be a factor, that remainder must be zero. ... The value of k is 3. Advertisement Advertisement GuyFromWalmart GuyFromWalmart Answer: k=3. Step-by-step explanation: If x-1 is a factor of f(x), then f(1) = 0. f(x) = x^3 - kx^2 + 2x. f(1) = (1)^3 ... WebApr 17, 2016 · 2 answers try completing the square. x^2+kx+2 = x^2 + kx + (k/2)^2 + 2 - (k/2)^2 = (x + k/2) + 2 - k^2/4 Now you have the vertex form of the parabola, with the vertex at x = -k/2. At that point, the minimum is 2 - k^2/4 So, now just set 2 - k^2/4 = 1 k^2/4 = 1 k^2 = 4 k = ±2 f (x) = x^2+2x+2 = (x+1)^2 + 1 f (x) = x^2-2x+2 = (x-1)^2 + 1

The more important thing is to know where your equation came from. The thing is that your function is equal to k x + 8 for x < 6, meaning that the limit lim x ↑ − 6 f ( x) is equal to lim x ↑ − 6 k x + 8 = k ⋅ ( − 6) + 8 while the upper limit lim x ↓ − 6 f ( x)
WebMay 31, 2024 · At ( − ∞, 1) and ( 1, + ∞), f is continuous since it has polynomial form. at x = 1, lim x → 1 − f ( x) = lim x → 1 − ( k x + 3) = k + 3 lim x → 1 + f ( x) = lim x → 1 + ( k 2 x 2 − 5) = k 2 − 5 thus, f is continuous at x = 1 if and only if k + 3 = k 2 − 5 or k 2 − k − 8 = 0 you can finish.
