Answer:

$f(3) =-8$

Step-by-step explanation:

Given

$f(x) = 2x + 5; x$

$f(x) =-3x + 1; x >1$

Required

Determine f(3)

f(3) implies that x = 3.

We make use of

$f(x) =-3x + 1$

Because x >1 (i.e. 3 > 1)

Substitute 3 for x in f(x) =-3x + 1

$f(3) =-3*3 + 1$

$f(3) =-9 + 1$

$f(3) =-8$

Q # 1 Graph the function Y = |X + 2| - 3

Svetllana [295]

First of all we know the Absolute Value Function that is:

$\left | x \right |= \left \{ {{x \ \ \ \ x \geq 0} \atop {-x \ \ \ \ x\ \textless \ 0}} \right.$

This is called the Parent Function of the Absolute Value Function.

From the equation:

$y=\left | x+2 \right |-3$

The term:

$\left | x+2 \right |$

means that the the Parent Function is shifted two units to the left.

On the other hand, the term:

$-3$

means that the function $\left | x+2 \right |$ is shifted three units downward. So the result is the graph shown below
