Each equation given below describes a parabola. which statement best compares their graphs? x = 2y^2 x = 8y^2

Is there an x intercept in the equation 60*1.15^x

Astudent draws two parabolas on graph paper. both parabolas cross the x-axis at (–4, 0) and (6, 0). the y-intercept of the first parabola 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? write your answer as a decimal rounded to the nearest tenth
