Question

Select "Yes" or "No" to indicate whether the ordered pair is on the graph of the function f(x)=−25x+1

Ordered Pairs:

Yes No
(1,625)
(0,−25)
(−1,−1)

Answer 1

(1,625) - No

(0,−25) - Yes

(−1,−1) - Yes

Blessed be

Answer 2

No, yes, yes

Explanation:

Given graph is of the function

`f(x) = -25^(x+1)`

To check whether the given pairs lie on the graph, we can substitute and check whether the point satisfies the equation of f(x)

(1,625)

Substitute 1 for x and 625 for y=f(x)

Left side = 625 and right side =
`-25^2 =-625`

Not equal hence no.

2) (0,-25)

Substitute 0 for x and -25 for y=f(x)

Left side = -25 and right side =
`-25^1 =-25`

Equal hence yes.

3) (-1,-1)

Substitute -1 for x and -1 for y=f(x)

Left side =-1 - and right side =
`25^0 =-1`

Equal hence yes.
