The function f(x) = x^2 is vertically stretched by a
factor of 4, then shifted 2
units left and 8 units up.
write the equation of the new
function in vertex form and
identify the vertex.

-12 > a

step-by-step explanation:

-11 > 1 + a

subtract 1 from each side

-11-1 > 1-1+a

-12 > a

let's fu(!

step-by-step explanation:

sample answer: you can determine whether each element of the domain is paired with exactly one element of the range. for example, if given a graph, you could use the vertical line test; if a vertical line intersects the graph more than once, then the relation that the graph represents is not a function.
