A function is defined by fx) = 5(2-x). What is f(-1)?

f ( x ) = 15

Step-by-step explanation:

Step 1:

f ( x ) = 5 ( 2 - x )          Function

Step 2:

f ( - 1 )          Given

Step 3:

f ( x ) = 5 ( 2 - ( - 1 ) )          Input x

Step 4:

f ( x ) = 5 ( 3 )          Combine Like Terms

f ( x ) = 15

Hope This Helps :)

15

Step-by-step explanation:

Since there is a -1 in place of the x, that means for every x value, x = the number in place of the x, so in this case every x would equal -1.

f(x) = 5(2-x)

f(-1) = 5(2+1)

f(-1) = 5(3)

f(-1) = 15

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.
