Question

PLEASE HELP ME.......

Answer 1

Put the first coordinate to the equation of a function.

`f(x)=3^x\\\\\left(-2,\ (1)/(9)\right)\to f(-2)=3^(-2)=(1)/(3^2)=(1)/(9)\qquad\text{On the graph}\\\\\left(-1,\ -(1)/(3)\right)\to f(-1)=3^(-1)=(1)/(3)\qquad\text{Not on the graph}\\\\(0,\ 3)\to f(0)=3^0=1\qquad\text{Not on the graph}\\\\(1,\ 3)\to f(1)=3^1=3\qquad\text{On the graph}\\\\(2,\ 6)\to f(2)=3^2=9\qquad\text{Not on the graph}\\\\(3,\ 27)\to f(3)=3^3=27\qquad\text{On the graph}`
