NEED HELP W/ THIS ACT PREP QUESTION: The curve y=0.005x^2-2x + 200 for 0 less than or equal to x less than or equal to 200 and the line segment from F (0, 200) to G (200, 0) are shown in the standard (x, y) coordinate plane below ( DRAWN BELOW) 1.) What is the y-coordinate for the point on the curve with x-coordinate 20? -160 -162 -164 -166 -168

can i ask you a question i'm confused what is `-` is this represent negative sign ?
Nnesha
  • Nnesha
well i don't think tahts a negative sign anyways replace x with 20 then solve

@Nnesha no, its just like A, B, C, D
Nnesha
  • Nnesha
oky cool then just substitute x for 20
