39. The graph of g(x)=−3(x−4)2+5 is translated 6 units left and 9 units down. What is the value of h when the equation of the transformed graph is written in vertex form?(A) −4(B) −2(C) 2(D) 10
Q. 39. The graph of g(x)=−3(x−4)2+5 is translated 6 units left and 9 units down. What is the value of h when the equation of the transformed graph is written in vertex form?(A) −4(B) −2(C) 2(D) 10
Identify Vertex Form and Vertex: Identify the original vertex form and the vertex of g(x).Original vertex form: g(x)=−3(x−4)2+5Vertex: (4,5)
Apply Translation to Vertex: Apply the translation to the vertex.Translation: 6 units left and 9 units down.New vertex: (4−6,5−9)=(−2,−4)
Write New Vertex Form: Write the new vertex form using the new vertex.New vertex form: g(x)=−3(x−(−2))2−4Simplified: g(x)=−3(x+2)2−4
Identify Value of h: Identify the value of h from the new vertex form.From g(x)=−3(x+h)2+k, h=2
