Question

please help...1. Given the following
quadratic equation, find
a. the vertex
b. the axis of symmetry
c. the intercepts
d. the domain
e. the range
f. the interval where the function is increasing, and
g. the interval where the function is decreasing
h. Graph the function.
y=x^2+6x+5

Answer 1

.......................x vertex = b/2a

Answer 2

axis of sym is x = b/2a

Answer 3

intercepts, solve the quad equation when y = 0

Answer 4

domain, what range of numbers can be used in the equation to give reasonable answers?

Answer 5

range, what range of values are produced from the above implementation, meaning how small and large can y be......

Answer 6

function is increasing of decreasing, use calculus

Answer 7

graph
