Find the equation of the tangent line to y = 1/ x^2 + 1 at x = 2

Use the inverse of the function y=x^2-18x to find the unknown value [tex]y = \sqrt{bx + c \: + d} [/tex]

In exponential growth functions, the base of the exponent must be greater than 1,how would the function change if the base of the exponent were 1? how would the fiction change if the base of the exponent were between 0and 1

What adds to be the bottom number but also multiplies to be the top number with 8 on the bottom and 15 on top
