Range is the value of y
f(x)=-x²+5
when x=-1, f(x)=-(-1)²+5=4
when x=2, f(x)=-(2)²+5=1
so 1<y≤4
the second piece: f(x)=2x-3
when x=2, f(x)=2(2)-3=1
when x=5, f(x)=2(5)-3=7
so 1≤y<7
union of the two parts of y: 1≤y<7
[1,7) is the answer.
Answer:
(15x - 4) units
Step-by-step explanation:
5x-2 + 4x-4 + 6x - 8
15x - 14
The number is 14. You can put it in an equation by writing 14 + (14 ÷ 2) = 21
Heres the answer you’re looking for.
y= -2x-4
The answer is 2/3 because the cat and the mouse had a child name catouse and then he built a space ship but yea the answer is really 2/3
