if the parent function is square root of x, describe the translation of this function square root x+7

Mathematics

kotykmax [81]3 years ago

The function y=\sqrt{x} sits with its starting point at the origin. The function y=\sqrt{(x-h)}+k is translated h units to the left or right and k units up or down. Since our radicand, the value under the square root sign, is x+7, putting that into our standard form it would be x-(-7) because minus a negative is a positive. So we move the parent graph to the left (-7 moves to the left) 7 units. There is no number k so our function is not moving up or down. Only to the left 7.

Find the area of each circle in terms of PI, the circles diameter is 2cm, what do i do know?
choli [55]
Given diameter 2cm
Find the area of a circle 
the formula for area of a circle 
A = pi r^2
the diameter is the radius times two 
so to find the radius given the diameter 2/2 = 1
radius is 1cm
pi is ~3.14
A = (3.14) * (1)^2
A = (3.14) * 1
A = 3.14
