The x-intercepts of a quadratic function are −3 and 5. What is the equation of its axis of symmetry?

x = −3
x = 1
x = 5
x = −15
help please this is due todayyy

x = 1

Step-by-step explanation:

Remember that the axis of symmetry is exactly halfway between the x-intercepts.  Find the average of -3 and 5 to obtain this x-value:  It is:

                         -3 + 5

x - intercept =  =  x = 1

                              2

b.-4 units

all you   do is count how many times you move

graph b

step-by-step explanation:

one solution- graph a (clear intercepting point.)

no solution- graph b (they're parallel, there will never be a point of interception.)

infinite solutions- graph c (all points intercept.)
