If y varies inversely as x and y = 7 when x = "-4" , find y when x = 2

Based on what i know about mean, this doesn't add up.

Which of the following describes the graph of y--4x-36 compared to the parent square root function? stretched by a factor of 2, reflected over the x-axis, and translated 9 units right stretched by a factor of 2, reflected over the x-axis, and translated 9 units left stretched by a factor of 2, reflected over the y-axis, and translated 9 units right stretched by a factor of 2, reflected over the y-axis, and translated 9 units left save and exit next submit

If f(x)=x+7 and g(x)=1/x what is (fog)(x)
