Identify the vertex and the y-intercept of the graph of the function. a. vertex, (-3,0); y-intercept, 4.5b. vertex, (-3,0); y-intercept, 1.5c. vertex, (3,0); y-intercept, 1.5d. vertex, (3,0); y-intercept 4.5

Plz determine whether the polynomial is a difference of squares and if it is, factor it. y2 – 196 is a difference of squares: (y + 14)2 is a difference of squares: (y – 14)2 is a difference of squares: (y + 14)(y – 14) is not a difference of squares
