If the tangent line to y = f(x) at (7, 4) passes through the point (0, 3), find f(7) and f '(7).
jarptica [38.1K]
Hello : 
f'(7) = the slope of the tangent line : let  A(7,4)    B(0,3)<span>
<span>the slope is :   (YB - YA)/(XB -XA)= (3-4)/(0-7) = -1/-7 = 1/7=f'(7)
the equation of the tangent line is :
y-3 = 1/7 (x-0)
 y = (1/7)x+3
the line tangent and the graph of : f </span></span><span>passes through the point A(7, 4)
x= 7 y=4 so : f(7) =4</span>

lubasha [3.4K]

Answer:

- 6x² - 2x + 1

Step-by-step explanation:

Given

(2x³ - 4x² - 3x + 5) + (- 2x³ - 2x² + x - 4)

Both parenthesis are distributed by 1 thus just remove them

= 2x³ - 4x² - 3x + 5 - 2x³ - 2x² + x - 4  ← collect like terms

= - 6x² - 2x + 1
