Q. Determine the value of y, if x is −1 .y=(x−2)2Answer:
Substitute x into function: Substitute the value of x into the function.We are given the function y=(x−2)2 and we need to find the value of y when x is −1.Substitute x=−1 into the function.y=(−1−2)2
Simplify expression: Simplify the expression inside the parentheses.Calculate the value inside the parentheses first, following the order of operations (PEMDAS/BODMAS).(−1−2)=−3Now the function becomes y=(−3)2
Square the result: Square the result obtained in Step 2.Square the value −3 to find y.y=(−3)2=9
