Hi,
f(x) = x. is reflected over the x-axis ====> g(x) = -
x
vertically compressed by a factor of 6====> g(x) = 6 x
vertically shifted 7 units up ====> g(x) = x + 7
BUT, it is not clear you need to make ONLY one function through all features or three function
If you need one function it will be g(x) = - 6 x + 7
I hope it is useful,
