1.what effect does replacing x with x−4 have on the graph for the function f(x) ? f(x)=|x−6|+2 the graph is shifted 4 units up. the graph is shifted 4 units down. the graph is shifted 4 units left. the graph is shifted 4 units right. 2.what are the coordinates of the hole in the graph of the function f(x) ? f(x)=x^2+3x−28/x+7 3.which graph represents the function?

Ques 1)

We know that the transformation of the type:

          f(x) → f(x-k)

shifts the graph of the parent function f(x) k units to the right.

Hence, on  replacing x with x−4 the graph of the function f(x) will be shifted 4 units to the right.

The correct option is:

       The graph is shifted 4 units right.

Ques 2)

For finding the hole of a rational function we first factor the numerator and denominator of the function and then the roots of the factor which is common to both numerator and denominator is the hole of the graph.

Here we have a rational function as:

which on factoring we get:

Hence, the common factor is:

and the root of the factor is:  x= -7

Hence, the hole in the graph of function f(x) is:

                 x= -7

Ques 3)

We are given a function h(x) as:

h(x)=  {x  if  x≤ -1

    and -x if x> -1

The graph is a straight increasing line with positive slope in the interval (-∞,-1] and there is a closed circle at (-1,-1)

and also the graph is a straight decreasing line with negative slope in the interval (-1,∞) and there is a open circle at (-1,1).

The correct graph is attached to the answer.

your answer is the frist one

hop i

so, converting firstly the mixed fractions to improper fractions and then "adding".
