Consider the function f(x)x^4 -32x^2 +2, -3 < or = to x < or = to 9. This function has an absolute minimum value equal to ? and an absolute maximum value equal to ?
The linear approximation at x=0 to f(x)= sqrt (7+6x) is y=
The function f(x)= (8x-7)e^2x has one critical number. Find it
If f(x)=x^3. Yhe equation of the tangent line to f(x) at x=4 is y=? Using this, we find our approximation for 3.8^3 is ?
u first distribute the -5 to the 3x n negative 4. so u get 6-15x+20=-49. u then combine 6 and 20 to get 26. so u get 26-15x=-49 then u subtra t 26 from buth sides and get: -15x=-75. then u divide -15 from both sides n x =5. hope this helped!!
