Answer:
See the explanation
Step-by-step explanation:
The function given to us is:
f(x) = (1/3)⁻ˣ
We can convert the negative power into positive one by interchanging the numerator and denominator.
f(x) = (3/1)ˣ
f(x) = 3ˣ
Substitute value for x= -3 , -2, -1, 0, 1, 2, 3
f(-3) = 3⁻³ = 0.037
f(-2) = 3⁻² = 0.111
f(-1) = 3⁻¹ = 0.333
f(0) = 3⁰ = 1
f(1) = 3¹ = 3
f(2) = 3² = 9
f(3) = 3³ = 27
f(4) = 3⁴ = 81
and so on
The table of the found values of f(x) or y for the corresponding values of x, along with their graph is given below.
0.15x + 100
x representing amount of text messages sent or received
Answer:
23
Step-by-step explanation:
f(x) = – 3x + 8
Let x = -5
f(-5) = – 3*-5 + 8,
= 15 +8
= 23
Answer:
The maximum is 3350$
Step-by-step explanation:
As carpenter he earns 35$ per hours
As web design he earns 75$ per hours.
We know that 75>35, so for maximum earning he need to work as web designer more.
He wants to vork as a carpenter at least 10h in week and he worls 50h per week. So for a maximum he works as web designer 50-10=40 hours.
So c=10 and w=40
The equation is:
35c+75w=35*10+75*40=350+3000=3350$
