If the function f (x) = 4x ^ 2-mx + 5 is an increasing function in the interval [- 2, positive infinity), then the value range of F (1) is

If the function f (x) = 4x ^ 2-mx + 5 is an increasing function in the interval [- 2, positive infinity), then the value range of F (1) is

f(X)=4x^2-mx+5=4(x-m/8)^2-m^2/16+5
If the axis of symmetry is x = m / 8, and the opening is upward, and it is an increasing function in the interval [- 2, positive infinity), then:
m/8
