Which is a valid prediction about the continuous function f(x)? f(x) ≥ 0 over the interval [-1, 1]. f(x) ≤ 0 over the interval [–[infinity], [infinity]). f(x) > 0 over the interval (–1, [infinity]). f(x) < 0 over the interval (0, 2).

the answer is c: divide the arc's degree measure by 360°, then multiply by the circumference of the circle.

i believe it is b and c. (side note, i got the same computer from k-12 lol i’m in 8th grade and this is my first year, will it get

step-by-step explanation:

step by step explanation: when u removing the parentheses and combined them that would be : x+3y-x-y=2y

answer: c

substitute in the values.

for a:

f(0) = 0 + 9

f(0) = 9

a is a solution.

for b:

f(7) = 14 + 9

f(7) = 23

b is a solution.

for c:

f (3) = 6 + 9

f(3) = 15

c is not a solution. it's supposed to be 14.

for d:

f(2) = 4 + 9

f(2)= 13

d is a solution.
