What is f(-2) for f(x)=1/2x²

Replace X with a couple different numbers, solve the equation for the y value:

IF X = 2, then y would be 1/2(2) +2 = 1+2 = 3

so the first point would be on (2,3)

X = 4, y = 1/2(4) + 2 = 2+2 = 4

The second point would be on (4,4)

Plot those two points and then draw a line thought both points.

Step-by-step explanation:

4 + 5 7/9= 9 7/9

step-by-step explanation:

3-4

step-by-step explanation:

the answer is 3-4 because both 45 and 60 has a multiple of 15.

45/3=15

60/4=15

therefore the odds against selecting a red is 4-3
