Answer:
Step-by-step explanation:
To find the product of the matrices: ×
Multiply rows of the first matrix by the columns of the second matrix.
(4 × (–2) + 2 × 7 4 × 5 + 2 × (–1))
After simplifying this, we get the product
Hence, ×

Answer:
The range of x values for which y is unique is 2·π
Step-by-step explanation:
For a function j: X → Y to be invertible, we have that for every y in Y, there is associated only one x which is an element of x
Hence, f(x) = cos(x - π/4) gives
the x intercept at two penultimate points of the graph of cos(x - π/4) are;
x = 2.36, and x = 8.64
x = 3/4·π, and x = 2.75·π =
Hence the range of x values for which y is unique is presented as follows
The range of x values for which y is unique = 2·π.
