Answer:
In Step 2, 90 should be multiplied by the quantity 10 – 12, not by 10
Step-by-step explanation:
90 * x - 90 * 12 = 90(x - 12)
From the question, x = 10
Hence,
90(10 - 12)
(90* 10) - (90 * 12) - - - > correct evaluation
900 - 1080
= - 180
Hence, both values in the bracket, that is 10 and - 12 should be multiplied by 90. Not just 10 alone.
Answer:
Step-by-step explanation:
f(x) = 1/2 .2^x
We need to fill the table by putting values of x in the given f(x)
x = -2
f(x) = 1/2 .2^(-2)
f(x) = 1/2.1/2^2
f(x) = 1/2.1/4
f(x) = 1/8 = 0.125
y=0.125
x = -1
f(x) = 1/2 .2^(-1)
f(x) = 1/2.1/2^1
f(x) = 1/2.1/2
f(x) = 1/4 = 0.25
y=0.25
x = 0
f(x) = 1/2 .2^(0)
f(x) = 1/2. 1
f(x) = 1/2 = 0.5
y=0.5
x = 1
f(x) = 1/2 .2^(1)
f(x) = 1/2.2
f(x) = 1
y=1
x = 2
f(x) = 1/2 .2^(2)
f(x) = 1/2.4
f(x) = 2
y=2
x = 3
f(x) = 1/2 .2^(3)
f(x) = 1/2.8
f(x) = 4
y=4
Now we will plot these points. The graph is shown in the graph below.
