Where is power function on TI 84?
All you need to do is go to your y= button, and type the function in as you would for any other function. You may need to use the “carrot” key (located below the “Clear” button on the upper right side of the calculator) a fair few times. Watch your parenthesis.

What is the formula for calculating regression?
Regression analysis is the analysis of relationship between dependent and independent variable as it depicts how dependent variable will change when one or more independent variable changes due to factors, formula for calculating it is Y = a + bX + E, where Y is dependent variable, X is independent variable, a is intercept, b is slope and E is residual.
How do you calculate the least squares regression?
The least squares regression equation is y = a + bx. The A in the equation refers the y intercept and is used to represent the overall fixed costs of production.
How do you calculate the line of regression?
Firstly,determine the dependent variable or the variable that is the subject of prediction. It is denoted by Y i.
How do you calculate the least squares line?
The standard form of a least squares regression line is: y = a*x + b. Where the variable ‘a’ is the slope of the line of regression, and ‘b’ is the y-intercept.
