Question

How do I find the real zeros of a function on a calculator?

Answer 1

Hint: We will start off by explaining the steps to solve. Then we will be mentioning the steps to solve such types of questions. Consider an unknown variable as $y$ to further simplify and evaluate the terms. Also, we will mention some rules as well.

Complete step by step solution:
We will start off by mentioning the steps to evaluate the zeroes of the function.
Now if your equation has something on the right side, subtract it from both sides so that the right hand is $0$. Now we will go for the value of $y$ . Then next we will enter the expression and then hit the graph. Now change the viewing window if necessary so that you can see where the graph crosses the x-axis. You will need to make sure that there is enough to the left and right of the x-intercept to select a point. Then we will continue on to the specific steps for your calculator. If there is more than one x-intercept, you may need to change your viewing window and repeat the steps for each x-intercept.

Note: While converting orders do not matter for addition and multiplication. But order is important for subtraction and division. Make sure that you read the statement twice before translating it to an expression. Pay extra attention to the statements where multiplication and division is involved.
