Check Explanation
Step-by-step explanation
We are told to point out the error in the calculation steps taken by this individual
y = a (x - 3)² - 5
-8 = a (2 - 3)² - 5
-8 = a(1) - 5
-8 = -4a
a = 2
y = 2(x - 3)² - 5
On careful observation, the error is noticed on the fourth step.
a(1) - 5 ≠ -4a
Rather, this should have gone in the manner of
y = a (x - 3)² - 5
-8 = a (2 - 3)² - 5
-8 = a (-1)² - 5
-8 = a(1) - 5
-8 = a - 5
We can then rewrite this as
a - 5 = -8
a = -8 + 5
a = -3
y = -3 (x - 3)² - 5
Hope thios Helps!!!
