Answer: f( -3)= 6
Step-by-step explanation:
Hi, to answer this question we have to replace the variable x for the value given (-3).
f(x) = x² + x
f( -3)= (-3)² + (-3)
Remember that if a negative number is raised to an even power, the result will be positive. in this case: (-3)²= 9.
f( -3)= 9 -3
f( -3)= 6
