1st:
f(x) = x^2.
f(x +1): Anywhere we see x we replace it with (x+1)
f(x+1) = (x+1)^2 , Expand
(x+1)^2 = (x+1)(x+1) = x^2 + 2x + 1= C.
2nd:
Noting general equation, y = mx + c
m = slope, c = vertical intercept.
From the graph, slope = (2,0) and (0, -4)
= (-4 -0) / (0 - 2) = -4/-2 = 2.
Vertical intercept, c = -4.
y = mx + c , y = 2x + (-4), y = 2x - 4 = D.
3rd:
f(x) = x^2 - x, f(-4). we would substitute x = -4.
f(-4) = (-4)^2 - (-4) = 16 + 4 = 20 = D.
Cheers.
Answer: second option
Step-by-step explanation:
The formula to convert the temperature from degrees Fahrenheit to degrees Celsius is:
Where C is the temperature in degrees Celsius and F is the temperature in degrees Fahrenheit.
Having the temperature 59 °F (degrees Fahrenheit), you need to substitute it into the formula to make the conversion from degrees Fahrenheit to degrees Celsius (C).
Then, you get:
<span>If the mixed number is scaled by 1/2 then, the original number will be divided by 2. That being said, the number then becomes 50% of the original value. Hence, scaling the number by 1/2 will make the number only 50% of its original value. </span>
