2 What is the graph of y-x 2. Which equation represents the line that passes through the point (-2.2) and is parallel to y-x 82 2 22x-3 x+3 4-2x +3 2. 3. Which statement about the function f(x)--3 is true? x+2 6. Given the functi its domain and rang D=(oo, oo) 2. x >2 and y 3, D = (2,00) 4. x 22 and y 1. Its domain does not include 2. 2. Its domain does not include 3. Its range does not include 1. 4. Its range does not include -2 4. IfRx)=2r2-3x+4/thenfe +3) is equal to 22-3x+ 7 2. 2x2 3x +13 3. 2x2 +9x +13 4. 2x2 +9x+ 25 2

Explanation / Answer

4. F(x) = 2x^2 - 3x + 4

Ans. We need to put (x+3) in function f(x)

F(x+3) = 2 (x+3)^2 - 3(x+3) + 4   

F(x+3) = 2 [x^2 + 9 + 6x ] - 3x - 9 + 4

F(x+3) = 2x^2 +18 + 12x - 3x -5

F(x+3) = 2x^2 + 9x + 13

Option 3 is the answer.
