Find f(-4) if f (x) = (x - 1)

5=x

Step-by-step explanation:

f(4)= f(x)

so, f(4)=(x-1)

then you just view the problem as, 4=x-1

so, 4+1=x because you need to get the x by itself so you have to move the 1 so it is with the 4. to get it to the other side you have to add it since is is being subtracted from the x. which makes it 5=x.

9.55 degrees.

step-by-step explanation:

the given angle is

1 cycle is equal to 2π radians. so 4π will be equal to two cycles.

5.166667π-4π = 1.166667π

hence, this angle goes a little more than negative x axis.

1.166667π-π= 0.166667π

hence, the reference angle is 0.166667π radians.

1 radian = 57.2958 degrees

now, in degrees, this should be equals to 9.55 degrees.
