Im pretty sure that it would be g(x)=7x+1 because that equals 8x and the other one equals 4x. You just leave the x because you dont know the number.

Answer:
Step-by-step explanation:
we are given a equation of parabola and we want to find the equation of tangent and normal lines of the Parabola
<u>finding</u><u> the</u><u> </u><u>tangent</u><u> </u><u>line</u>
equation of a line given by:
where:
- m is the slope
- b is the y-intercept
to find m take derivative In both sides of the equation of parabola
divide both sides by 2y:
substitute the given value of y:
simplify:
therefore
now we need to figure out the x coordinate to do so we can use the Parabola equation
simplify:
we'll use point-slope form of linear equation to get the equation and to get so substitute what we got
simplify which yields:
<u>finding</u><u> the</u><u> </u><u>equation</u><u> </u><u>of </u><u>the</u><u> </u><u>normal</u><u> </u><u>line</u>
normal line has negative reciprocal slope of tangent line therefore
once again we'll use point-slope form of linear equation to get the equation and to get so substitute what we got
simplify which yields:
and we're done!
( please note that "a" can't be specified and for any value of "a" the equations fulfill the conditions)
Answer:
$45???
Step-by-step explanation:
we are given
vertical asymptote at x=-3
so, there will be x+3 in the denominator
we are given zeros at x=-2
so, there will x+2 in the numerator
so, we can set up function as
we can select any one point
and then we can find 'a'
(0,1)
so, we can plug f(x)=1 and x=0
and find 'a'
now, we can plug back
and we get
