||a|| is called the norm of a. The answer is square root of 58. Hope it helps
Divisor is -4
Use coefficients 1 12 38 26
Bring down 1 multiply by -4 and add to 12 =8
Multiply 8 by -4 and add to 38 = 6
Multiply 6 by -4 and add to 26 = 2 which is the remainder
looks like 1 12 38 26
-4 -32 -24

so answer A of x squared + 8x + 6 +R2 is correct
The function f(x)=-3x follows a linear form y=ax+b, where a is the slope and b is the y-intercept. From our function:
f(x)=-3x
f(x)=-3x+0
slope, a=-3 and y-intercept is 0. This implies that the function is a linear function, thus the domain and range will be:
domain:
(-∞,∞)
Range:
(-∞,∞)
