which function is graphed below? f(x) = –cos(x) f(x) = cos(x) f(x) = sin(x) f(x) = –sin(x)

f(x)= sin(x) on E2020 the graph with 2 curves (~)

The answer is...

f(x)= sin(x) on E2020

for ex: the reciprocal of 3/4 is 4/3. it is the opposite.

reciprocal definition:

a mathematical expression or function so related to another that their product is one; the quantity obtained by dividing the number one by a given quantity.

answer: the answer is one

step-by-step explanation:

pemdas, in this situation there is no parenthesis or exponents so you go to multiplication, 1x1=1, then division 1/1= 1 then addition 1+1=2 then subtraction 2-1=1
