Graph f(x)=|x−2|+3 .<br><br> Use the ray tool to graph the function.
maks197457 [2]

Answer:

Answer:

The graph will be 2 units away from the origin on positive x-axis and three units upward from the origin towards y-axis.

Step-by-step explanation:

Here is a graph attached with it.

To graph \left | x-2 \right |+3 we know that positive \left | x \right | is a V shaped from the origin.

Key points:

  • To move rightward there must be a negative inside the parentheses.
  • And to move upward we must have positive b = constant.

If we have to move towards x-axis then we must have negative inside it.

And if we have to move upward in y-axis positive we must have positive constant value.

So the graph will be three units upward and two units rightward with a V-shaped ray.

Michelle tried to solve an equation step by step. \begin{aligned} t-\dfrac35&amp;=\dfrac45\\\\ t-\dfrac35+\dfrac35&amp;=\dfrac45
valentinak56 [21]

Answer:

Step 2

Step-by-step explanation:

Michelle's step in trying to solve the equation is given below:

\begin{aligned} t-\dfrac35&=\dfrac45\\\\ t-\dfrac35+\dfrac35&=\dfrac45+\dfrac35&\green{\text{Step } 1}\\\\ t&=1&\blue{\text{Step } 2} \end{aligned}

Michelle made a mistake in Step 2.

The right hand side of Step 1:  \dfrac45+\dfrac35\neq 1

Rather, the correct sum is:

\dfrac45+\dfrac35=\dfrac75\\\\=1\dfrac25
