The negative sound is not inside the brackets so the y value changes by a factor of negative one. Hence the answer is (-3,-4)

Sorry, misread the question Y=-f(x) X =-3 Y=-f(-3) Y= -4 So answer is (-3,-4) Tldr, the graph has been flipped vertically so keep your X value consistent and make your y value negative

As we have y=-f(x) we have the negative value for f(x) Say you had f(x)=x², then y=-f(x) would be y=-x² So we keep the X value consistent F(4) = -3 So y= -f(4) = --3 = 3 So the value is (4,3)
