f(g(-1)) = - 3
Evaluate g(-1) and substitute into f(x)
g(-1) = (-1)² -7(-1) - 9 = 1 + 7 - 9 = - 1
f(g(-1)) = (-1) - 2 = - 3

Albert Einstein's general theory of relativity<span> is one of the most elevated achievements of 20th-century physics. Published in 1916, it explains that what we perceive as the force of gravity in fact arises from the curvature of space and time. </span>Einstein <span>proposed that objects such as the sun and the Earth change this geometry. </span>
