Construct a matrix that triples the height, width, and length of an objective in 3d

Step-by-step explanation:

Our dimension vector is:

We need a matrix that returns another 3x1 vector, where only each component is 3 times the original value.

Let's see for x:

if

then:

a*x+b*y+c*z=3*x then, b=c=0 and a=3

d*x+e*y+f*z=3*y then, d,f=0 and e=3

g*x+h*y+i*z=3*z then g,h=0 and i=3

the answer is c

hope this !

f(x) = y

f(-3) = -5
