Answer: c.
Answer:
2.
Domain: all real values of x
Range: f(x)》-4
3.
Domain: all real values except x = 0
Range: All real values except f(x) = 0
Step-by-step explanation:
2.
Domain: all real values of x
Range: f(x)》-4
Because this is a concave up quadratic with a minimum turning point at (0,-4)
3.
Domain: all real values except x = 0
Range: All real values except f(x) = 0
Since x is in the denominator, it can't be 0
For f(x) = 0, x has to be infinity
Step-by-step explanation:
#12)
1 5/8= 8x1 = 8 + 5 = 13
13/8 = 13÷8 = 1.625 and it not a repeating decimal
#13)
5/6 = 5 ÷ 6 = 0.833333 and is a repeating decimal
Answer:
13i/5
Step-by-step explanation:
25z^2+140=-29 subtract 140 from both sides
25z^2=-169 now square root both sides.
=
a negative root forms i
5z=13i
z=13i/5
