Question

Answer the question below based on the two quadratic functions.Function 2хyFunction 1f(x) = x2 + 4x - 3-7-8-2.-1012.-7-41Which function has the graph with the smaller minimum value and what is the minimum value?Function 1 has the smaller minimum value of -2.Function 2 has the smaller minimum value of -1.Function 1 has the smaller minimum value of -7.O Function 2 has the smaller minimum value of -8.

Answer 1

1. Plotting the function or creating a table with values.

This is what you did, and you got that for x=-2 the functions reaches the minimum, to y= -7

Now, since you already know the minmum value for the first function, you can see that the first answer is false while the third one is true. But, is that value (-7) smaller than the minimum for function 2?

Looking at the table, we can see that function 2 reaches the minimum for x = -1, and it is equal to y = -8.

Since -8 < -7, function 2 minimum is smaller than function 1 minimum.

Then, answer #4 is the correct one.
