Question

Select the correct answer. The function h(x) = 31x2 + 77x + 41 can also be written as which of the following? A. h(x) + 41 = 31x2 + 77x B. y + 41 = 31x2 + 77x C. y = 31x2 + 77x + 41 D. y = 31x2 + 77x − 41

Answer 1

`y=31x^2+77x+41`

which agrees with option C in your list of possible answers.

Explanation:

Since normally functions are represented on the x-y plane, it is common to replace h(x) with the "y" variable of the vertical axis where its values will be represented (plotted). Then the expression can be also written as follows:

`h(x)=31x^2+77x+41\\y=31x^2+77x+41`
