Rewrite the function by completing the square f(x)=x^2-4x-26

leonid [27]

Answer:

(x - 2)² - 30

Step-by-step explanation:

To complete the square

add/subtract ( half the coefficient of the x- term )² to x² - 4x

f(x) = x² + 2(- 2)x + 4 - 4 - 26 = (x - 2)² - 30

Which translation maps the vertex of the graph of the function f(x) = x2 onto the vertex of the function g(x) = x2 + 2x +1?

jarptica [38.1K]

Answer:

Option B is correct

Left 1 unit.

Explanation:

According to the graph theory of transformation:

y = f(x+k)= $\left \{ {{k>0 shift graph of y= f(x) left k unit} \atop {k$

Given the parent function: $f(x)=x^2$

and the function $g(x)=x^2+2x+1$

we can write it as:

g(x)= $(x+1)^2$ [ ∴ $(a+b)^2 = a^2+2ab+b^2$ ]

Therefore, vertex of the graph of the function $g(x)=(x+1)^2$ is 1 units to the left of the vertex of the graph of the function $f(x)=x^2$ .
