Answer:
- Blue - 18, green - 50, with photo - 37
Step-by-step explanation:
<u>Total number = 150</u>
- Blue = 150/8 = 18 (integer part)
- Green = 150/3 = 50
- Spaceman Spiff autograph = 150/4 = 37 (integer part)
Answer: 1/3 (x + 6)
Explanation: given f(x) = 3x - 6.
Let y = f(x) and so y = 3x - 6.
Trade places between x and y.
x = 3y - 6
Solve for y
x + 6 = 3y
y = x + 6/3
Now the new y is the inverse and so y = f-1(x)
f-1(x) = 1/3(x + 6)
Answer:
f(3) = 4
f(-7) = -26
Step-by-step explanation:
Hi there!

To find f(3), replace every x with 3:

Therefore, f(3)=4.

To find f(-7), replace every x with -7:

Therefore, f(-7)=-26.
I hope this helps!

Answer:
0
Step-by-step explanation:
The function is defined everywhere except at x=-6. The limit value is the function value at that point.
f(6) = (6^2 -36)/(6 +6) = 0/12 = 0
The limit of the function is 0 as x → 6.
Answer:
Step-by-step explanation:
discriminant = (-13)² - 4·2·15 = 49
discriminant > 0 so there are two real roots
