Use the definition f ′(x) = h0f(x + h) - f(x)h to find the derivative. f(x)=x+2

NNADVOKAT [17]

Answer:

f'(x) = 1

General Formulas and Concepts:

Calculus

Limit Properties: $\lim_{n \to a} c = c$
Definition of a Derivative: $f'(x)= \lim_{h \to 0} \frac{f(x+h)-f(x)}{h}$

Step-by-step explanation:

Step 1: Define

f(x) = x + 2

Step 2: Find derivative

Substitute: $f'(x)= \lim_{h \to 0} \frac{((x + h) + 2)-(x+2)}{h}$
Distribute: $f'(x)= \lim_{h \to 0} \frac{x + h + 2-x-2}{h}$
Combine like terms: $f'(x)= \lim_{h \to 0} \frac{h}{h}$
Divide: $f'(x)= \lim_{h \to 0} 1$
Evaluate: $f'(x)= 1$

Answer:

Reflected about the y-axis and then rotated 90° counterclockwise

Step-by-step explanation:

(x , y) to (-x , y) --> reflected over y-axis

then (-x , y) --> (-y, -x) -->90 degrees rotation counterclockwise

So answer is the last one
