precal homework I need help please Homework Statement Homework Equations 1.T(t)=4t/(t^2+1)+98.6 find T,t 2.P(x)=1500/(x^2-6x+10) The Attempt at a Solution 1.4t/t^2+1=98.6 sub t=2 4t/2(2)+1=98.6 T=8/5+98.6 1.6+98.2=100.2 not sure how to find t I don't know how to...

o really so is it like f(x)=(x+h)^3-7(x+h)^2+(x+h)+1 then I simplify

Homework Statement evaluate f(x+h) expand and simplfy f(x)=x^3-7x^2+x+1? Homework Equations f(x+h) The Attempt at a Solution my attempt (f(x+h)+f(x)+1 x^2(x+h)+x+1 x^2(x+7)+x1 im lost I'm not sure how to do this
