number 1 is the answer circle FA
Answer:





Whenever finding a rule, figure out what x+1 relates to in terms of y (aka the slope). Also, figure out the y-intercept (0,<em>y</em>)
<u>Example:</u>
x+1 = y+2.
Slope: 2 ÷ 1 = 2.
The y-intercept is (0,9)
This would make the rule y=2x+9
Answer:(a) n=0.233
Step-by-step explanation:
Given
We Know according to Taylor tool life

V=cutting speed
T=tool life
n=tool life exponent
c=constant



taking log both side

n=0.233
(f+g)(x)= f(x) + g(x) = 5x-6 + x^2-4x-8 = x^2+x-14
