Answer:
(-1,8)
(4,-27)
Step-by-step explanation:
y+7x=1
Let x = -1 and find y
y+7(-1)=1
y -7 =1
Add 7 to each side
y-7+7 = 1+7
y = 8
(-1,8)
Let x = 4 and find y
y+7(4)=1
y +28 =1
Subtract 28 from each side
y+28-28 = 1-28
y = -27
(4,-27)
f(3) = 1.9
Solution:
Given function:
To find f(3):
Substitute x = 3 in the given function.
Let us first simplify 
.
Apply exponent rule: 
The value of 
. (using calculator)
Substitute this value in f(3).
f(3) = 1.9
Hence the value of f(3) is 1.9.
