Select the true statement. A. Only function f is even.
B. Neither function is even. C. Only function g is even. D. Both functions are even.

Function g is even

Step-by-step explanation:

Even functions have graphs that are symmetrical about the y-axis, so the second (blue) graph is even.  The other (the red) function is not symmetric with respect to the y-axis and so is not even.  The correct answer is C:  Only function g is even.

341

step-by-step explanation:

all you have to do is 9x31 (which equals 279) and then 20x31 (which equals 620). then you have to subtract. 620-279=341.
