This is so important! HELP PLEASEEE. Consider the quadratic: y = 2(x+1)(x-3) a) Find the location of the x-intercepts
b) Find the equation for the axis of symmetry.
c) Find the location of the vertex
d) Sketch the parabola, clearly showing the vertex and the 2 x-intercepts.

2. explain in words how you plot the point (4, −2) in a rectangular coordinate system.

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

Aspacecraft can attain a stable orbit 300 kilometers above earth if it reaches a velocity of 7.7 kilometers per second. the formula for a rocket's maximum velocity v in kilometers per second is vequalsminus0.0098tplusc ln upper r, where t is the firing time in seconds, c is the velocity of the exhaust in kilometers per second, and r is the ratio of the mass of the rocket filled with fuel to the mass of the rocket without fuel. find the velocity of a spacecraft whose booster rocket has a mass ratio of 20, an exhaust velocity of 2.1 km/s, and a firing time of 15 s. can the spacecraft achieve a stable orbit 300 km above earth?
