Which function has the greater rate of change?

function 1
function 2

*picture listed below*

Function 1

Step-by-step explanation:

Function 1 has rate of change of

(15.75 - 14.25)/(1 -(-1)) = 0.75. This was calculated using slope formula.

Function 2 has rate of change of 5/6, which is 0.833.

step-by-step explanation:

second option

step-by-step explanation:

the measures of a triangle equal 180. use that to find x.

2x+3x+4x=180

9x=180

9x/9=180/9

x=20

now you know x, you know angle a is 40°, angle b is 60°, angle c is 80°.

because angle a is 40°, the first option doesn't work.

because angle b is 60°, the second option does work.

when you add angle a and b, you get 100°. complementary means it equals 90°, so the third option doesn't work.

when you add angle a and c, you get 120°, which is not 100.
