Q. Three points on the graph of the function f(x) are {(0,1),(1,2),(2,4)}. Which equation represents f(x) ?f(x)=(x+1)2f(x)=2xf(x)=2xf(x)=x+1
Test Equation f(x): Test the first equation f(x)=(x+1)2 with the given points.We will plug in the x-values from the points into the equation and see if the resulting y-values match the given points.For the point (0,1):f(0)=(0+1)2=12=1This matches the y-value of the first point.For the point (1,2):f(1)=(1+1)2=22=4This does not match the y-value of the second point, which is f(x)=(x+1)20.Since the second point does not match, we can conclude that f(x)=(x+1)2 is not the correct equation.
