### 9) \( a(x) \) was transformed to create \( d(x) \) by reflecting it over the x-axis.### 10) The value of
is
.### 11) \( d(x) = -a(x) \)
Explicação
## Step 1: Analyze the transformation from \( a(x) \) to \( d(x) \)### We need to determine how the function \( a(x) \) is transformed to become \( d(x) \). By comparing the corresponding
-values for each
in both tables, we observe:- For
, \( a(-1) = -3 \) and \( d(-1) = 3 \).- For
, \( a(0) = 0 \) and \( d(0) = 0 \).- For
, \( a(1) = 3 \) and \( d(1) = -3 \).- For
, \( a(2) = 6 \) and \( d(2) = -6 \).### The pattern shows that \( d(x) \) is the negative of \( a(x) \). Therefore, the transformation applied is a reflection over the x-axis.## Step 2: Identify the value of
### From the transformation identified, \( d(x) = -a(x) \). Here,
represents the factor by which \( a(x) \) is multiplied to obtain \( d(x) \). Since \( d(x) = -a(x) \), the value of
is
.## Step 3: Write \( d(x) \) in terms of \( a(x) \)### Based on the analysis, the relationship between \( d(x) \) and \( a(x) \) can be expressed as:
