Answer:
c. [-1, infinity)
Step-by-step explanation:
the domain the interval or set of valid x values (while the range is the same for the valid y values).
what is the smallest value of x we see for the graph ?
for x values we need to look left and right.
and the more left the value, the smaller it is.
so, in other words, what is the left-most x value e can find ?
x = -1
that is the "starting point" of the function. there is no functional value for any smaller x.
and then clearly, the function goes on and on to the right without any boundary in sight. so, it keeps going to the right in all eternity, that means it goes to infinity.
therefore the answer.
keep in mind that "infinity" is not a number, only a concept. so, when writing "infinity" at an interval end, it is not included (and we use a round bracket).
Answer:
21
Step-by-step explanation:
I have done this question before.
Answer:
Step-by-step explanation:
(-x + 3) - (4x - 10)
= - x + 3 - 4x + 10 (because when you see the minus sign you have to change all the sign inside the bracket)
= -5x + 13 (this step is just subtract -x and -4x and 10 + 3)
When given a function and asked to find the value of a number, in this case g(12), simply plug 12 into all x places in the equation:
g(12)=3(12+8)
g(12)=36+24
g(12)=60
The pattern starts at 2/14 and increases by 1/14 each node, so the next fraction is 6/14 which simplifies into 3/7
