Q. Three points on the graph of the function f(x) are {(0,2),(1,3),(2,4)}. Which equation represents f(x) ?f(x)=x2+2f(x)=x−2f(x)=2⋅(23)xf(x)=x+2
Test Equation f(x): Test the first equation f(x)=x2+2 with the given points.For (0,2), f(0)=02+2=2.For (1,3), f(1)=12+2=3.For (2,4), f(2)=22+2=6.Check if the calculated values match the given points.
Check Calculated Values: Since f(2)=6 does not match the given point (2,4), the first equation f(x)=x2+2 is not the correct representation of f(x).
Test Equation f(x): Test the second equation f(x)=x−2 with the given points.For (0,2), f(0)=0−2=−2.For (1,3), f(1)=1−2=−1.For (2,4), f(2)=2−2=0.Check if the calculated values match the given points.
Check Calculated Values: Since f(0)=−2 does not match the given point (0,2), the second equation f(x)=x−2 is not the correct representation of f(x).
Test Equation f(x): Test the third equation f(x)=2×(23)x with the given points.For (0,2), f(0)=2×(23)0=2×1=2.For (1,3), f(1)=2×(23)1=2×23=3.For (2,4), f(2)=2×(23)2=2×49=29.Check if the calculated values match the given points.
