Evaluate the following functions.
bezimeni [28]

Functions are written in terms of variables.  The value of the function given if x = -4 is 50

<h3>Functions and values</h3>

Functions are written in terms of variables. Given the function shown;

f(x) = 3x^2 - x

If the value of x is -4, hence;

f(-4) = 3(-4)^2 - (-2)

f(-4) = 3(16) + 2

f(-4) =48 + 2

f(-4) = 50

Hence the value of the function given if x = -4 is 50
