Answer:
Step-by-step explanation:
For two matrix P and Q, the product, say PQ is defined when:
The number of columns of P = The number of rows of Q
Since A is a 2×2 matrix and B is also a 2×2 matrix
Thus both AB and BA are possible.
So AB is:
BA is:
Y α x²
y = kx²
64 = k*4²
64 = k*4*4
64 = 16k
64/16 = k
4 = k
k = 4
y = kx²
y = 4*6²
y = 4*6*6
y = 144
Answer: 1 (-4)
Step-by-step explanation: f(x) is a function of x giving you a y value. 1/2 f(x) means you're halving every y value that plugging in x gives you.
