For this, you will be multiplying g(-4) and h(-4) together.

$(g*h)(-4)=(2(-4)-1)(3(-4)-1)$

Firstly, do the multiplications within the parentheses: $(g*h)(-4)=(-8-1)(-12-1)$

Next, do the subtractions: $(g*h)(-4)=(-9)(-13)$

Lastly, multiply -9 and -13, and your answer should be $(g*h)(-4)=117$

27 students in all 4:5 packed lunch. how many students packed lunch

bonufazy [111]

$\bf \stackrel{total}{27}\qquad 4:5\qquad \cfrac{4}{5}\implies \cfrac{4\cdot \frac{27}{4+5}}{5\cdot \frac{27}{4+5}}\implies \cfrac{4\cdot 3}{5\cdot 3}\implies \cfrac{\stackrel{packed~lunch}{12}}{\stackrel{did~not~pack~lunch}{15}}$

Determine if the function is an even function an odd function or neither y=2x^4+2x^2

irakobra [83]

Answer:

This function would be even.

Step-by-step explanation:

You can tell a function is even if you plug in -x for x and then simplify and it is the same function. This is the case below.

y = 2x^4 + 2x^2 ----> Plug in -x

y = 2(-x)^4 + 2(-x)^2 ----> Simplify

y = 2x^4 + 2x^2

You'll notice the simplified version is exactly the same as the original, which makes it odd.
