Ryker is given the graph of the function
y= 1/2x^2 - 4 . he wants to find the zeros of the function but is unable to read them exactly from the graph. find the zeros give answer to nearest tenth

x= 2.8   and x= -2.8

Step-by-step explanation:

To find out the zeros, we replace x y with 0 and solve for x

Add 4 on both sides

Multiply by 2 on both sides

8= x^2

Now we take square root on both sides

x= +-

x=2.82843 and x=-2.82843

x= 2.8   and x= -2.8

answer:   x*94 +688*6   = 267*100

94x+4128=26700    

94x=22572     /94

x=240.128
