For the following problem, (i) graph f and g in the same coordinate system; (ii) solve f(x) = g(x) algebraically to two decimal places; (iii) solve f(x) > g(x) using parts i and ii; (iv) solve f(x) < g(x) using parts i and ii.f(x) = -0.8x(x - 8), g(x) = 0.4x + 3.2; 0 ? x ? 10 
A. (i) f is the curve, g is the line 
(ii) 0.58, 6.92
(iii) 0.58 < x < 6.92
(iv) 0 ? x < 0.58 or 6.92 < x ? 8
B. (i) f is the curve, g is the line 
(ii) 0.61, 7.98
(iii) 0.61 < x < 7.98
(iv) 0 ? x < 0.61 or 7.98 < x ? 8
C. (i) f is the curve, g is the line 
(ii) 0.58, 7.98
(iii) 0.58 < x < 7.98
(iv) 0 ? x < 0.58 or 7.98 < x ? 8
D. (i) f is the curve, g is the line 
(ii) 0.61, 7.02
(iii) 0.61 < x < 7.02
