Given the following functions, find the indicated values. f(x)= 7 - 9x
(a) f(-9) (b) f(0) (c) f(2)
(a) f(-9)=

a = 88, b = 7, c = -11

Step-by-step explanation:

a)

f(x) = 7 - 9x

f(-9) = 7 - 9(-9)

f(-9) = 7 + 81

f(-9) = 88

b)

f(x) = 7 - 9x

f(0) = 7 - 9(0)

f(0) = 7

c)

f(x) = 7 - 9x

f(2) = 7 - 9(2)

f(2) = 7 - 18

f(2) = -11

step-by-step explanation :

we know that

the measurement of the outer angle is the semi-difference of the arcs which comprises

in this problem

m< xzy is the outer angle

substitute the values

the measure of angle xoy is equal to

> by central angle

substitute the value
