F(×)=3×^2-3× g (×)=-5×-1 find f (-4) and g (7)

If g(x) = x+1/ x-2 and h (x) =4 - x , what is the value of ( g*h) (-3)?

Lena reflected this figure across the x-axis. she writes the vertices of the image as a'(−2, 8), b'(−5, 6), c'(−8, 8), d'(−4, 2).

The roots of the function f(x) = x2 – 2x – 3 are shown. what is the missing number?
