How do you solve this ?

1 answer:

5 0

When given a value of the variable, we replace each instance of the variable in the problem with that number. In this case, the expression becomes:

$\frac{3^2 + 3}{3 - 1}$

After this, we merely need to simplify the answer.

$\frac{9 + 3}{3 - 1}$

$\frac{12}{2}$

Simplifying 12/2 gives us the answer 6.

Answer:

Rx)=1/3x^2

Step-by-step explanation:

A horizontal stretch is simply making the parabola of the parent function wider, it's kind of like changing the slope of a line to make it less steep.

In the graph, the red line is the parent function and the blue line is the horizontally stretched function. See how the blue line appears to be stretched (horizontally).
