Liesa wants to graph k(x) = 2(x + 3)^2 - 5. She thinks that the vertex of the parabola should be (6,-5), because 2*3=6, and there's a (-5) at the end.
She plots that vertex, and then graphs a parent function upward from
there. She ends up with the graph shown. Explain whether you agree or
disagree with Liesa's work, and what you would have done differently, if
you disagree. Answer specifically about the vertex, y-intercept, and the
shape and orientation of the parabola.*

Acable company wants to provide cell phone service for residents on an island. the function for the cost of laying the cable from the island to the mainland is c(x)= 6.500 square root x2+4, where x represents the length of the cable in feet. what are the domain and range of the function? a) domain: all real numbers range: all real numbers greater than or equal to 17,000 b) domain: all real numbers greater than or equal to 0 range: all real numbers greater than or equal to 17,000 c) domain: all real numbers greater than or equal to 0 range: all real numbers greater than or equal to 13,000 d) domain: all real numbers greater than or equal to 13,000 range: all real numbers greater than or equal to 0

Simone claims the initial value and y-intercept are the same thing on a graph. is she correct? if you know that a line has a slope of and a y-intercept of 7, what is the equation for that line in slope-intercept form?

X2 + y 2 = 36 x + y = 6 solve the system of equations.
