The graph of two functions is shown.
graph of f of x equals negative x squared plus x and g of x equals x minus 1
If x = −1 is a solution to f(x) = −x2 + x and g(x) = x − 1, why is it also a solution to f(x) = g(x)?
a
It is a solution to f(x) = g(x) because it is the x-intercept of the two graphs.
b
It is a solution to f(x) = g(x) because it is the y-intercept of the two graphs.
c
It is a solution to f(x) = g(x) because it is the x-coordinate where the two graphs intersect.
d
It is a solution to f(x) = g(x) because both graphs are negative at x = −1.
