Question

Graph the function y = x square + 2x - 3 and identify the range if the domain is all real numbers. Draw a chart to show at least three ordered pairs that are on the graph.

Answer 1

I think:
y = (x-1) (x+3)

so 1,0, -3,0 and 0,-3 The Domain is all real so where {y element all R where y>or=-4}

Answer 2

i could be wrong on the 0,-3....pretty sure the rest is right

Answer 3

that help any?

Answer 4

thank u

Answer 5

domain is all real numbers because it is a polynomial

Answer 6

range of \(y=x^2+2x-3\) is from the second coordinate of the vertex up to infinity

Answer 7

what r the three ordered pair
