The value of the function when x = 1/2 is r(1/2) = 3 2/3
How to evaluate the function?
The equation of the function is given as:
r(x) = -2/3x + 4
The equation r(x) = r(1/2) means that
x = 1/2
Substitute x = 1/2 in r(x) = -2/3x + 4
r(1/2) = -2/3 * (1/2) + 4
Evaluate the product
r(1/2) = -1/3 + 4
Evaluate the difference
r(1/2) = 3 2/3
Hence, the value of the function when x = 1/2 is r(1/2) = 3 2/3
