Quadratic Functions - Vertex and Standard Forms

USING -b/2*a = h , Find the value of h using the formula -b/2*a DO THE MATH

NOW YOU KNOW X = H AND YOU FOUND IT , YOU CAN REPLACE X IN STANDARD FORM EQUATION Y = X^2-4X + 5 WHAT IS THE VALUE FOR Y =

AFTER YOU FOUND X AND Y , WHICH IS H AND K, WHAT IS YOUR VERTEX? , USE THE GeoGebra Sliders TOOL TO PLACE THE RED PARABOLA g(x) on top of Black Parabola f(x)

The graph BELOW shows the function   𝙛(𝙭)=−𝟭𝟬𝙭^2 +𝟳𝟬𝟬𝙭−𝟲𝟬𝟬𝟬 and shows the profit a company earns for selling headphones at different prices. What is the maximum profit the company can expect to earn? Find the Vertex to find the Maximum Profit at the Best Selling Price (Exact Number no Estimating)
