Well what i think you're asking here...I apologie if I'm wrong but what I did was
f(-1) = 4 * 7^t = 4/7
and
f(2) = 4 * 7^t = 196.
Is this what you wanted if not I can...try another way.
X hour and 7 dollars per hour
x = hour
7(x) is your function
thank you for Anlian for pointing it out.. there is 4 hours
so x = 4
plug in 4 in x. 7(4)
7 x 4 = 28
28 is your answer
hope this helps

Step-by-step explanation:
Find the area of the rectangle, then add up the area of the triangle.
The area of the rectangle
= 5 × 12
= 60 cm²
The <u>base</u> of the triangle
= 12 - 9
= 3 cm
The <u>height</u> of the triangle
= 9 - 5
= 4 cm
The area of the triangle
= (3 × 4) ÷ 2
= 6 cm²
The total area of the figure
= 60 + 6
= <u>66 cm²</u>
