The calculated values of the functions are r(3) = 2 and r(-9) = 10
How to evaluate the value of the function
From the question, we have the following parameters that can be used in our computation:
r(x) = −2/3x + 4
For r(3), we have
r(3) = −2/3 * 3 + 4
Evaluate
r(3) = 2
For r(-9), we have
r(-9) = −2/3 * -9 + 4
Evaluate
r(-9) = 10
Hence, the values of the functions are r(3) = 2 and r(-9) = 10
