Question

What is the rang for the function : F(x)=x^2+4x ? Hint ; Find the Vertix .

Answer 1

the vertex would count as the absolute minimum of the function

Answer 2

so it would be [y,infinity)

Answer 3

you can get the range from the vertex of this parabola...
since this is a parabola that opens upwards, it has a minimum value... the vertex occurs at -b/(2a) = -2. plugging this into F, F(2)=(-2)^2 + 4*(-2) = -4.
so (-2, -4) is your vertex.
so your range is [-4, infinity)

Answer 4

*F(-2)

Answer 5

so Will it be all real number s

Answer 6

no it wouldnt...

Answer 7

A. y </equal to -4
B. y >/equal to -4
c . y >/equal to 4
D. all real numbers

Answer 8

@dpaInc / @alexwee123 Help

Answer 9

did you find the vertex yet?

Answer 10

Nope !
