Question 1 (50 points)

Your friend, Taylor, missed class today and needs some help identifying solutions to systems. Explain to Taylor how to find the solution(s) of any system using its graph.



Question 2 (50 points)

Taylor graphs the system below on her graphing calculator and decides that f(x)=g(x) at x=0, x=1, and x=3. Provide Taylor some feedback that explains which part of her answer is incorrect and why it is incorrect.

f(x)=2x+1g(x)=2x2+1

Answer 1

Answer:

Step-by-step  explanation:

guess i will do Q.2 first

f(x)=2x+1 n g(x)=2x^2+1,

at x=0, f(0)=1=g(0)

x=1, f(1)=3=g(1)

in general a straight line like f(x) and a parabola like g(x) will intersect at most 2 times. in this case, at x=0 n 1.

x=3, f(3)=2(3)+1=7, g(3)=2(3)^2+1=19

f(x)<>g(x) at x=3
