Use the parent function f(x) = x2 to fill in the blanks. a. f(x) = -X2 is a across the x-axis.
b. f(x) = is a horizontal translation right by 3 units.
C. f(x) = x2 + 6 is a vertical translation up by___?

a) reflection across the x-axis

b) f(x) =( x-3)²

c) f(x) = x² + 6 is a vertical taranslation up by '6' units

Step-by-step explanation:

Explanation

Given that the parent function

              f(x) = x²

a) f(x) = x² is rotation across the x-axis then the new function

 f(x) = - x²

b) ) f(x) = x² is a horizontal translation right by '3' units then the function is changes to f(x) = (x-3)²

c)  

f(x) = x² is a vertical translation up '6' units then the function is changes to f(x) = x² +6  

197 students (rounded to the nearest whole number)

Step-by-step explanation:

first I divided 11 by 114 to find out how much girls there are to every one boy and my answer was 10.36 (rounded to the nearest 2 d.p).

next I times it by eight according to the ratio given, my answer was 83 (rounded to the nearest whole number)

finally, I just added 114 and 83 together to get the total number of students and my answer to that was 197 (rounded to the nearest whole number)

hope it helped
