the eqn is y+4-6x^2-3x

y+4-6x^2-3x = 0 ***

first you the y-value when x=0(so y=-4) and then when you find the equation of the tangent at any piont (aka, the slope) you use the slope, and your x and y value and sub them into the y=mx+b eqn to get it or you can use slope=(-4-y)/(o-x)

only one problem. we're looking for the equation of a straight line. so it couldn't have any squared values in it

true, okay the answer is y=3x+4
anonymous

that was considered the wrong answer when i submitted

okay, and what's the ex in front of the eqn?
anonymous

g(x) = e^x(−4 + 3x + 3x^2)
anonymous

e to the power of x?

whoa thats wierd, i didnt even consider that

just get the derivative using product rule, then sub 0 in for x and find the slope at that point, and then use y=mx+b, no big.
