If g(x)=2[x]-1, what is g(-2.3)? a.) -7 b.) -5 c.) -4 d.) -3

The floor function returns the largest integer not greater than the given value. Substitute the given number and evaluate.

The appropriate choice is

... A.) -7

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.
