Answer:
False
Step-by-step explanation:
If f(x) is a function , then for each value of x there should be a single y values
For input 0 there is a output 0
for input 10, the output is 2
for input 15, output is 3
For input 5, we have two output 1 and 3
for single input 5, the function cannot have two outputs 1 and 3
So this f(x) is not a function
1. a. (ii) 1/27
1st one is already given, I will give you the answer to the second one,
³√27/9²
= 3/81
= 1/27

it would be a negative
(+-) cancels itself out to be 0 and (-) is negative so adding a negative to 0 will give you a negative. Hope this helps (:
state the y-intercept and the slope of the following linear equations.
think of y=mx+b
m is the slope
b is the y-intercept
1) y=3/4x-2
slope= 3/4
y-intercept= -2
2) y= -x+3
slope= -x
y-intercept= 3
3) y=3x+5
slope=3
y-intercept=5
4) y=1/2x-5
slope= 1/2
y-intercept= -5
5) y= -2x-4
slope= -2
y-intercept= -4
6) y= -1/5x-1
slope= -1/5
y-intercept= -1
7) y=3/2x+4
slope=3/2
y-intercept=4
8) y=x+1
slope=x
y-intercept=1
9) y=2x+5
slope=2
10) y=8/5x+3
slope=8/5
y-intercept=3
11) y= -3x-4
slope= -3
12) y= -2x-2
