7-28.

Graph the system below. Homework Help ✎

Convert both inequalities into equations and simplify into graphing form.

$y=2x^2+1$

A parabola with vertex at $(0,1)$ and vertically stretched by $2$.

$1+x−y=3x−2y−4\\y=2x−5$

A line with slope $2$ and y-intercept $(0,−5)$.

Graph both equations, then test points to find which area is the solution to the system of inequalities.

$1+x−y\ge3x−2y−4\\ \ \ \ \ \ \ \ \ \ \ \ \ \ \ y<2x^2+1$
