Answer:

A. F(x)is an even function so both ends of the graph go in the same direction.

D. The leading coefficient is negative so the left end of the graph goes down.

Step-by-step explanation:

Even function:

For every value of x, f(x) = f(-x)

In this question:

We are given the following function:

f(x) = -4x^6 + 6x^2 - 52

Testing if it is even:

f(1) = -4(1)^6 + 6(1)^2 - 52 = -4 + 6 - 52 = -50

f(-1) = -4(-1)^6 + 6(-1)^2 - 52 = -4 + 6 - 52 = -50

Since f(1) = f(-1), it is even.

Since it is even, both ends of the graph go in the same direction, so option A is correct, while option B is wrong.

Options C and D:

The leading coefficient, is -4(which multiplies x with the highest exponent). Since it is negative, it goes to negative infinity as x increases, that is, the left end goes down, and option D is correct while C is not.

Together, teammates Pedro and Ricky got 2673 base hits last season. Pedro had 275 more hits than Ricky. How many hits did each p
Andre45 [30]
Rickey got 1199 and Pedro got 1474. I got that by subtracting 275 from 2673 to get 2398. Than you divide 2398 to get 1199 which is Rickey's answer but to get Perdro you have to add 275 to get his answer of 1474.

To increase an amount by 5.4% what single multiplyer would you use
photoshop1234 [79]
If the multiplier was 1.54, then you would get more then 1 and a half times your original amount.

Do 100% + 5.4% to get 105.4%.
Turn this into a whole number (divide by 100) to get 1.054 as your multiplier.
