Question

write the quadratic function in vertex form using the graph(Note: none of these graphs havebeen vertically stretched or compressed so (a) should be 1, you must decide if (a) is positive or negative ​​

Answer 1

f(x) = -(x+1)-3

Explanation:

Standard formula: f(x) = a(x-h)+k

Since the graph is reflected across the y-axis, we have negative 1 for a. Then since the graph is shifted 1 unit to the left h is 1. Since k moves the graph up or down we have minus 3.
