(Enter NONE in any unused answer blanks.) x-intercepts x, v)- X(smallerx-value) X(larger x-value) y-intercept x,y 5. Conesder the following. 3r-- 27x + 9 nx) a) State the domain or the Tunction. (Enter vour answer vsing interval notation.) b) Idantify all intercapts. (Enter NONE in any unusad answar banks.) x-intercepts (x, y) = (smaller x-value) erger -value y-intercept (x, v)- Find any vertical and slant asymptotes. (Enter NONE if there is no asymptote.) sant asymptote y=

Explanation / Answer

4. x intercept,

TO find the x intercept, we have to set f(x) to 0 and solve for x .

x2-x-20=0

(x-5)(x+4)=0

x=5,-4

x intercept (-4,0),(5,0)

y intercept, x=0

f(x)=-20/-4=5

y intercept (0,5)
