Answer:
W1 = ( -75, 20, 1 , 0 )
W2 = ( 25, -7 , 0, 1 )
Step-by-step explanation:
attached below is the remaining part of the solution
for a homogenous system of equation ; Ax = 0
x1 + 4x2 -5x3 + 3x4 = 0
-x2 + 20x3 -7x4 = 0 note: x3 and x4 are free variables
we can take x3 = 0 and x4 = 1 , hence ; x2 = -7
∴ x1 - 28 + 3 = 0 = x1 = 25
W2 = ( x1 ,x2, x3, x4 ) = ( 25, -7 , 0, 1 )
now lets take x3 = 1 and x4 = 0 hence x2 = 20 , x1 = -75
∴ W1 = ( x1 , x2 , x3, x4 ) = ( -75, 20, 1 , 0 )
After performing the transformation on f(x) = |x|+7; reflected across the x-axis and translated 4 units up. We get the function g(x) = -(|x| + 7) + 4
<h3>What is a function?</h3>It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.
We have a function:
f(x) = |x| + 7
First we reflect the function f(x) across the x-axis
Multiply the function by -1
F(x) = -(|x| + 7)
To translated 4 units up add 4 to the function.
g(x) = -(|x| + 7) + 4
Thus, after performing the transformation on f(x) = |x|+7; reflected across the x-axis and translated 4 units up. We get the function g(x) = -(|x| + 7) + 4
