F(4) is function notation that means the value of y when x = 4.
Replace x with 4 in the expression and evaluate the right side.
f(x) = 3x - 15
f(4) = 3(4) - 15
f(4) = 12 - 15
f(4) = -3
D. 40 percent
Adding everything up that he spent money on, we get $744 dollars. That's out of a total of his $1240 dollars.
So we can find out how much money he has left by subtracting the total from the amount he spent.
1240 - 744 = 496
$496 dollars is the amount of money he has left. To find out the percentage he has left, put the remaining amount over the total times 100.
So, 496/1240 = .4
.4 × 100 = 40 percent. Hope that helps!

Step-by-step explanation: since i helped can i have brainlist please :D
For this case we have the following transformation:
Assume k> 0
To graph f (x) + k, move the graph k units up.
Applying the transformation we have:
y = x ^ 2 + 5/2
Answer:
The equation of the new parabola is:
y = x ^ 2 + 5/2
