f(x) = -x + 2
f(-1) This means that they want you to find the value of f(x) or y when x = -1.
f(x) = -x + 2 Substitute/plug in -1 into "x" since x = -1
f(-1) = -(-1) + 2 (two negative signs cancel each other out and become positive)
f(-1) = 1 + 2
f(-1) = 3
The additive inverse of something is the number that, if you add it to the original number, you get 0.
The additive inverse of 5, for example, is -5. 5 plus -5 = 0.
You should be able to see how additive inverses are always going to be just the original number with the signs changed. (i.e., times -1)
The additive inverse of -4a would be 4a. -4a + 4a = 0.
<span>f(x) = x^2 + 1, find f(a + 1)
so
</span> f(a + 1) = (a+1)^2 +1
f(a + 1) = a^2 + 2a + 1 + 1
f(a + 1) = a^2 + 2a + 2
Answer:
20
Step-by-step explanation:
4(2x - 31)=36
4×2x-4×31=36
8x-124=36
8x=36+124
8x=160
x=160/8
x=20
