Answer:

a = 9, b = 3, c = 0

Step-by-step explanation:

f(x) = (1/3)^x

a = f(-2) = (1/3)^-2= 9

b = f(-1) = (1/3)^-1 = 3

c = f(0) = (1/3)^0 = 1

whenever something is to the power of 0, the answer will always be 1

13. Line m has no y-intercept, and its x-intercept is (-5, 0). Line n has no x-intercept,
Lyrx [107]

Line m equation is x+5 = 0 .

Line n equation is y+3 = 0 .

<u>Step-by-step explanation:</u>

Here , we have Line m has no y-intercept, and its x-intercept is (-5, 0). Line n has no x-intercept,  and its y-intercept is (0, 3). Let's find out equation of both line step by step:

Equation of line m:

Line m has no y-intercept , that means line is never intersecting y-axis which is only possible when line is parallel to y-axis , also this line have x-intercept as (-5,0) i.e. cuts x-axis at x = -5 .

⇒ x = -5

⇒ x+5 = 0

∴ Line m equation is x+5 = 0 .

Equation of line n:

Line n has no x-intercept , that means line is never intersecting x-axis which is only possible when line is parallel to x-axis , also this line have y-intercept as (0,3) i.e. cuts y-axis at y = 3 .

⇒ y = -3

⇒ y+3 = 0

∴ Line n equation is y+3 = 0 .
