Answer:
Option (D)
Step-by-step explanation:
If a function f(x) is represented on a graph and we follow the transformation as,
f(x) →
1). If k ≥ 1, graph of the parent function f(x) will be stretched vertically by a factor k.
That means the transformed graph will be narrower.
2). If 0 < k < 1, graph will be vertically compressed or the transformed function will show a wider graph.
Following this rule,
f(x) → shows k =
[Since 0 <
< 1]
Therefore, transformed form will be wider.
Option (D) will be the answer.
Answer:
d. −7/32
Step-by-step explanation:
The expression that we have to evaluate in this problem is:
We have to evaluate this expression for:
x = -2
y = 4
We start by rewriting the expression by rewriting it using the following:
So the expression can be rewritten as
Now we observe that:
Therefore, by substituting x = -2 and y = 4 into the expression, we find:
