Consider two distinct real numbers, a and b. We define the function
a. Show that is a quadratic function. What is the coefficient of ? b. Explain why . Conclude that , for some constant k . Find k , using your work in part (a). c. For which values of t is the matrix invertible?
Therefore, the determinant of the given matrix is given by,
a). The coefficient of is .
C) The matrix invertible value of t is .
a) Show that is a quadratic function.
Thus, f is a quadratic function, the coefficient of being localid="1659512383139" .
b) We compute:
