When a refection is done about x-axis, the values of the abscise x remain identical & the value of ordinate just change their signs: A(-5,-3); A'(-5,+3) B(-6,-1); B'(-6,+1) C(-3,-1); C'(-3,+1) D(-2,-3); D'(-2,+3)
2) A'B'C'D' is translated 3 UNITS RIGHT, that means the ordinated of A'B'C'D' are the same but the abscises have been increased by 3 UNITS ;
So, if "d" equals the diameter, we need to plug in 1.5 for "d". The equation now looks like: f(h) = 2(1.5) +4.3. Now if you multiply, it's: f(h) = 3 + 4.3, which then is: f(h) = 7.3. The height would be 7.3 in, when the diameter is 1.5 in. Hope this helps =). Have a great day!
