What is f(x) = 2x2 + 28x – 5 written in vertex form?

f(x) = 2(x + 7)2 – 19
f(x) = 2(x + 7)2 – 103
f(x) = 2(x + 14)2 – 14
f(x) = 2(x + 14)2 – 98

Vertex form of f(x) is:

Step-by-step explanation:

The vertex form of the function f(x) is:

f (x) =, where (h, k) is the vertex of the parabola.

We are given f(x)=

Now, converting the above equation in required form

Hence, Vertex form of f(x) is:

the answer is the option b

the range is all real numbers

step-by-step explanation:

we know that

the absolute value parent function is equal to

see the attached figure to better understand the problem

so

a. it is v-shaped > is true

b. the range is all real numbers > is not true

because the range is the > [0,∞)

all real numbers greater than or equal to zero

c. it goes through the origin > is true

d. the domain is all real numbers > is true

step-by-step explanation:

relating to or denoting a system of numbers and arithmetic based on the number ten, tenth parts, and powers of ten.
