QuestionMatch each function hh with its transformation: (a) h(x)=f(x)+ch(x)=f(x)+c, (b) h(x)=f(x)ch(x)=f(x)-c, (c) h(x)=f(x+c)h(x)=f(x+c), (d) h(x)=f(xc)h(x)=f(x-c).

Studdy Solution

STEP 1

Assumptions1. The functions h(x)h(x) are transformations of a base function f(x)f(x). . The constant cc is positive.
3. The transformations can be either horizontal or vertical shifts.

STEP 2

Let's start with the first function h(x)=f(x)+ch(x)=f(x)+c.
This function represents a shift of the base function f(x)f(x), but we need to determine whether it's a horizontal or vertical shift, and in which direction.

STEP 3

The transformation h(x)=f(x)+ch(x)=f(x)+c adds a constant cc to the output of the function f(x)f(x).
This means that for any input xx, the output of the function h(x)h(x) is cc units higher than the output of the function f(x)f(x).

STEP 4

Therefore, the function h(x)=f(x)+ch(x)=f(x)+c represents a vertical shift of ff, cc units up.

STEP 5

Next, let's analyze the function h(x)=f(x)ch(x)=f(x)-c.
This function subtracts a constant cc from the output of the function f(x)f(x).
This means that for any input xx, the output of the function h(x)h(x) is cc units lower than the output of the function f(x)f(x).

STEP 6

Therefore, the function h(x)=f(x)ch(x)=f(x)-c represents a vertical shift of ff, cc units down.

STEP 7

Now, let's analyze the function h(x)=f(x+c)h(x)=f(x+c).
This function changes the input to the function f(x)f(x) by adding a constant cc.
This means that for any input xx, the function h(x)h(x) evaluates ff at a point cc units to the left of xx.

STEP 8

Therefore, the function h(x)=f(x+c)h(x)=f(x+c) represents a horizontal shift of ff, cc units to the left.

STEP 9

Finally, let's analyze the function h(x)=f(xc)h(x)=f(x-c).
This function changes the input to the function f(x)f(x) by subtracting a constant cc.
This means that for any input xx, the function h(x)h(x) evaluates ff at a point cc units to the right of xx.

STEP 10

Therefore, the function h(x)=f(xc)h(x)=f(x-c) represents a horizontal shift of ff, cc units to the right.
So, the transformations are as follows(a) h(x)=f(x)+ch(x)=f(x)+c represents a vertical shift of f,cf, c units up. (b) h(x)=f(x)ch(x)=f(x)-c represents a vertical shift of f,cf, c units down. (c) h(x)=f(x+c)h(x)=f(x+c) represents a horizontal shift of f,cf, c units to the left. (d) h(x)=f(xc)h(x)=f(x-c) represents a horizontal shift of f,cf, c units to the right.
