Hey guys my brother told me you guys are very helpful so help me

I'm having trouble on this

Take the last two digits in your id and add them together. Call this number n.

a)

Write an equation for a quadratic function that has x-intercepts (n,0) and (n+1,0)

and a y-intercept (0,n+2). Provide the formula and the graph.

b) Write an equation for a quadratic function that has vertex (n,-n) and y-intercept (0,3).

Provide the formula and the graph.

N = 7

how would I even start this equation?

Thx
