Question

A function relating these variables is M, left bracket, x, right bracket, equals M(x)= . So M, left bracket, 8, right bracket, equals M(8)= , meaning if 88

Answer 1

The value of M(8) = 4.

The function M(x) = 7 - 3x is a linear function that represents a constant (7) minus a multiple of a variable (3x).

To evaluate the function at x = 8, you simply substitute 8 for x in the function:

M(8) = 7 - 3(8) = 7 - 24 = 4

So, M(8) = 4.
