x=0.2 answer
26) Let f(x)=x4−1x2−1 for x≠−1,1 .
a. Sketch the graph of f .
b. Is it possible to find values k1 and k2 such that f(−1)=k and f(1)=k2 , and that makes f(x) continuous for all real numbers? Briefly explain.
27) Sketch the graph of the function y=f(x) with properties i. through vii.
i. The domain of f is ( −∞,+∞ ).
ii. f has an infinite discontinuity at x=−6 .
iii. f(−6)=3
iv. limx→−3−f(x)=limx→−3+f(x)=2
v. f(−3)=3
vi. f is left continuous but not right continuous at x=3 .
vii. limx→−∞f(x)=−∞ and limx→+∞f(x)=+∞
Answer:
y= - 2
Step-by-step explanation:
This is correct
7x+20+9x-2=180
16x+20-2=180
16x-18=180
+18 to both sides...
16x=198
divide by 16 to both sides...
x=12.375!
