Answer:
4
Step-by-step explanation:
Given function is :
f(x) = 5(x² - 4x + _) + 15
We need to fill the gap.
In order to make complete the square, we will use the completing the square method.
Here we take the coefficient of x
that is -4
take half of -4 = -2
Now square the -2 = (-2)² = 4
add and subtract the 4
So, 4 belongs in the blank to complete the square.
That's the final answer.
By rounding to the nearest one it means round to the nearest whole number. So basically, the number 0.7414 rounded to the nearest whole number would be 1.
