What is the axis of symmetry of h(x)= 5x^2+40x+ 64?
andrezito [222]

Answer:

Axis of symmetry is  x = -4

Step-by-step explanation:

h(x)= 5x^2+40x+ 64

Use the formula for axis of symmetry:   x = -b/(2a)

Here,  a = 5,  b = 40,  c = 64

so

x = -40/(2*5) = -40/10 = -4

Axis of symmetry is  x = -4
