Let f(x)=x+1 and define s(x) to be the slope of the line through the points (0,0) and (x,f(x)). a. Evaluate: s(5)
and s(-2); b. Find an equation for s(x) in terms of x.
Note that fractional answers must be expressed like -5/6, and answers with exponents like (x^2-1)/(x+3). Use lower case letters.and do not use spaces in your answers.
Find the slope of the line through the points P and Q when:
a. P(1,3) and Q(x, x2+3x-1)
b. P(x, x2+3x-1) and Q(x+h, (x+h)2+3(x+h)-1)
Answer: (Write the variables or letters first, then the number, say x+h+1)
