4n + 5n +3
Coefficients are:
Terms are:

4 and 5 are coefficients. terms are 4n, 5n, and 3

Step-by-step explanation:

well, because 4 and 5 have a variable next to them, they are coefficients. the terms in the equation are the seperate pieces that form the equation, if that makes sense

h is the x-coordinate of the vertex

step-by-step explanation:

we have

in this function

the point represent the vertex of the function

so

h is the x-coordinate of the vertex

k is the y-coordinate of the vertex
