What are the roots of 2x^2+4x+7? Use the quadratic formula. Show your work

The roots are

Step-by-step explanation:

we have

To find the roots equate the equation to zero

so

we know that

The formula to solve a quadratic equation of the form

is equal to

in this problem we have

so

substitute in the formula

Remember that

so

simplify

therefore

The roots are

i think it is 18

step-by-step explanation:

a, b, c, d are correct.

step-by-step explanation:

we have g(x) = 3 and are required to find which option is a translation of g(x).

now, 'translation' is a transformation which means to shift the function in any direction and the general form of translation is g(x) + k, where k is any real number.

so, according to the options we see that all are correct as they satisfy the general form of translation.

also, it can be seen from the graph below that the function g(x) = 3 is shifted from its position in all the four options.
