Accepted Solution
A:
Let[tex]f(x)=x^{2}-1[/tex][tex]g(x)=x+1[/tex]we know thatThe function f(x) is a vertical parabola open upwardthe vertex is the point [tex](0,-1)[/tex] ------> is a minimumThe function g(x) is a linear equationThe y-intercept is the point [tex](0,1)[/tex] -----> for [tex]x=0[/tex] find the value of g(x)thereforethe answer in the attached figure
