Evaluate each expression if a=2, b=3 and c=4<br><br> A.) 2a+4b-c<br> B.) 6(a+c)-b
djyliett [7]

Answer:

Step-by-step explanation:

A.) 2a+4b-c:  Replacing a with 2, b with 3 and c with 4, we get:  

    2(2) + 4(3) - (4) = 4 + 12 - 4 = 12

B.) 6(a+c)-b:  Replacing a with 2 and c with 4, we get 6(2 + 4) - 3.

The work inside parentheses should be done first, resulting in 6(6) - 3.

This comes out to 33.

Which of the following functions is not odd?
guapka [62]
For odd function f(-x)= -f(x)

1) f(-x)= sin(-x) = -sin(x)=-f(x)       sin is odd function
2) f(-x) = sin(-2x) = -sin 2x=-f(x)
3) f(-x)= (-x)³+1 = -x³ +1 (not an odd function)
To be an odd function, it should be like this:
if a function is (x³+1), to be odd f(-x) should be -(x³+1)=-x³-1
4) f(x)= x/(x²+1) 
f(-x) = (-x)/((-x)²+1)= -x/(x²+1)=-f(x)
So, f(-x) gives - \frac{x}{x^{2}+1},
that means that  f(x)= x/(x²+1)  is an odd function.
5)f(x) = ∛(2x)

f(-x) = ∛(2*(-x)=∛(2x*(-1)) = ∛(2x)*∛(-1)=- ∛(2x)= -f(x)
