Step-by-step explanation:
<u>Given function</u>
The points (-1, 1/6) and (1, 2/3) lie on the graph
<u>Substitute the values of x and y to get the system of equations:</u>
- 1/6 = c*a^(-1) ⇒ 1/6 = c/a ⇒ a = 6c
- 2/3 = c*a^1 ⇒ 2/3 = ac
<u>Substitute a and solve for c:</u>
- 2/3 = 6c*c
- 1/9 = c²
- c = √1/9
- c = 1/3
<u>Find a:</u>
<u>The equation of the function:</u>
Answer:
y-intercept (0,11/5)
x-intercept (11/2,0)
Step-by-step explanation:
The y-intercept is obtained when the x-coordinate equals 0 (x=0)
so the y-intercept is (0,11/5)
The x-intercept is obtained when the y-coordinate equals 0 (y=0)
In this case
0 = -(2/5)x+11/5---->(2/5)x = 11/5 ----> x=(5*11)/(5*2) = 11/2
So the x-intercept is (11/2,0)
