Answer:
f(x) = -5x-3
Step-by-step explanation:
f(x) = ax + b
f(2)=-13 & f(-3) =12
2a + b = -13
-3a+ b = 12
_________-
5a = -25
a = -5
b= -13+10= -3
so the formula of f(x) = -5x -3
The ones place value is four
Answer:
Step-by-step explanation:
cos ^-1(0)=(2n+1) π/2
where n is an integer.
if 0 ≤α ≤2 π
n=0,1
cos ^-1(0)=π/2,3π/2
