Question

How do I graph a function like \[x = {y^2} - 3y + 5\] on a \[TI - 84\] ?

Answer 1

Hint: We need to know how to enter the given quadratic equation in the \[TI - 84\] . Also, we need to know how to enter the variable with square, variable and constant which are involved in arithmetic operations like addition/ subtraction/ multiplication/ division the \[TI - 84\] to solve this type of question.

Complete step-by-step answer:
The given equation is shown below,
 \[x = {y^2} - 3y + 5\]
At first, we have to insert a generic quadratic into the \[TI - 84\]
Next, we would enter \[x = {y^2} - 3y + 5\] by using the keys in the following order.
First, we would press the \[y,t,theta,n\] key for \[y\]
Next, we would press the \[{y^2}\] key.
Next, we would enter a subtraction followed by \[3\] then the \[y,t,theta,n\] key again
Finally, we would enter an additional key followed by a \[5\]
Lastly, we would press the grey graph button on the top right.
In this question we take \[x = 0\]
By using this process we can easily solve the given equation as it is in question.

Note: We would remember the process to enter the quadratic formula and to enter the variable, variable square, constant with its sign like addition or subtraction sign. Note that after entering all the terms in the equation we would press the grey colour graph button which was located on the top right to draw the graph.
