What does a negative number in front of "x squared" do to the graph:

y = x^2

Which steps could be part of the process in algebraically solving the system of equations, y+5x=x^2+10 and y=4x-10

Find a parametrization for the curve「and determine the work done on a particle moving along γ in r3 through the force field f: r^3--r^3'where f(x,y,z) = (1,-x,z) and (a) im (γ) is the line segment from (0,0,0) to (1,2,1) (b) im (γ) is the polygonal curve with successive vertices (1,0,0), (0,1,1), and (2,2,2) (c) im (γ) is the unit circle in the plane z = 1 with center (0,0,1) beginning and ending at (1,0,1), and starting towards (0,1,1)

Perform the indicated operation and write the answer in the form a + bi. (-5 + 2) + (3 - 6i)
