1. Let f(x)=x^2-4x+3 Calculate f(x+h). Show all work.2. Let f(x)=x^2-4x+3. Calculate f(-x). Show all work.3. Algebraically calculate the x and y intercept(s) (if any) of the equation.y=x^2-2x-244. Algebraically find the domain for the following function. Write your answer in either interval or set builder notation.f(x)=square root 6x-12

solve for y to determine if y is a function of x. If it is, express it using function notation. What is the domain?  x+y^2=2

Determine where the function is concave upward. ​   ​f(x)x^4-2x^3+7x+5
