Answer:
Step-by-step explanation:
Function given
Range = -5
- f(x) = -5
- 4x - 1 = -5
- 4x = 1 - 5
- 4x = -4
- x = -1
Domain is -1
Answer:
its 6.75
Step-by-step explanation:
3/10 = 0.3
2/5 = 0.4
0.3 / 0.4 = 0.75
0.75 x 9 = 6.75
hope i helped
Let f(x)=x3(exponent)+kx2(exponent)+x+5
When f(x) is divided by (x+2) the remainder is =3
This is the remainder theorem
so,f(−2)=−8+4k−2+5=3
4k=3+5=8
k=2
Step-by-step explanation:
i. 3x-1=20
or, 3x= 21
x= 7
ii. 3x+1= 22
3x= 21
x= 7
iii. 2x-5=99
2x= 104
x=52
iv. g(3)= 3+5/2= 11/2
g(0)= 0+ 5/2=5/2
g(-3)= -3+5/2 = -1/2
x+5/2= 0
so, x= -5/2
