Describe the domain and range of y=2(3)^x-2+5

15 and 14.7 are 1 apart, so 15 – 14.7 must be 1.

Astudent draws two parabolas both parabolas cross the x axis at (-4,0) and (6,0) the y intercept of the first parabolas is (0,-12). the y intercept of the second parabola is (0,-24) what is the positive difference between the a values for the two functions that describe the parabolas
