The numeric values for the given functions are as follows:
<h3>How to find the numeric value of a function or of an expression at a given point?</h3>
To find the numeric value of a function at x = a, we replace each instance of the variable, usually x, in the function by the desired value of a.
Function f(x) is defined by:
f(x) = x².
For the numeric value at x = 1/3, we replace the lone instance of x by 1/3, hence:
f(1/3) = (1/3)² = 1/9.
Function g(x) is defined by:
g(x) = 2x.
For the numeric value at x = 4, we replace the lone instance of x by 4, hence:
g(4) = 2(4) = 8.
For the numeric value at x = -3, we replace the lone instance of x by -3, hence:
g(-3) = 2(-3) = -6.
