What is the average rate of change between x = -1 and x = 1?

Answer 1

Hi Wooo, You forgot to write the function

when ask you what the average rate of change between two points or two given x is, in fact you need to find the slope

slope = ( y₂ - y₁ ) / ( x₂ - x₁)

_{When X = -1 -------> y = ? you did not write the function. By replacing -1 to the given function you find Y2}

when X = 1 ------> y =? _{you did not write the function. By replacing 1 to the given unction you find y1}

_{slope = ( Y2 - y1 ) / ( -1 -1 )}

_{slope = ( Y2 - y1 ) / ( -2)}

_{I hope it is useful,}
