Draw the graph of y = x^3+3 for values of x between –3 and 3. Use your graph to estimate the value of y when x = -2.5.

Substitute different values of x in y=3x and get corresponding y coordinates.

Substitute different values of x in y=3x and get corresponding y coordinates.Such as (0,0),(1,3),(2,6),(−1,−3),(−2,−6)

Substitute different values of x in y=3x and get corresponding y coordinates.Such as (0,0),(1,3),(2,6),(−1,−3),(−2,−6)Now, when x=−2 then y=−6 .

answer: x=60
