Use the piecewise function below to evaluate the points f(–3), f(0), and f(–1). {9x, x−4,x<−1x≥−1
Question 17 options:

f(–3) = –7, f(0) = –0, and f(–1) = 5

f(–3) = –27, f(0) = –4, and f(–1) = 5

f(–3) = –7, f(0) = –4, and f(–1) = –1

f(–3) = –27, f(0) = –4, and f(–1) = –5

Given:

The piecewise function is:

To find:

The values of .

Solution:

In the given piecewise function,

for and for .

Putting in , we get

Putting in , we get

Putting in , we get

The required values are .

Therefore, the correct option is D.

options a,b,c are the right answer.

step-by-step explanation:

a linear parent function is always represented as y = x

if we write this function in the form of y=mx+c

⇒

or  

now if we plot a graph we will find these characteristics:

1) y intercept of the graph is zero so its a straight line passing through origin.

2) as we can see in both the forms of function written, values of x and y may be either positive or negative for the positive slope means points on the graph are either in first quadrant or in third one.

3) it's slope is one.
