Answer:

D and E

Step-by-step explanation:

f(x) = (x - 3)² - 25

x intercepts occur when y = 0

0 = (x - 3)² - 25

25 = (x - 3)²

±5 = x - 3

x = 8, or -2

A) g(x) = 2x + 2

0 = 2x + 2

x = -1 Nope

B) h(x) = 2x + 6

0 = 2x + 6

x = -3 Nope

C) q(x) = -4x + 11

0 = -4x + 11

x = 11/4 Nope

D) r(x) = -3x - 6

0 = -3x - 6

x = -2 YES

E) w(x) = 3x - 24

0 = 3x - 24

x = 8 YES

Consider the function f(x)=10^x and function g(x)=f(x+4). How will the graph of function g differ from the graph of function f?

Jobisdone [24]

Answer:

Shifts 4 units to left

Step-by-step explanation:

Given:

$\displaystyle \large{f(x)=10^x}\\\\\displaystyle \large{g(x)=f(x+4)=10^{x+4}}$

Accorded to transformation rules:

f(x + a) is shift to left a units.
f(x - a) is shift to right a units.
f(x) + a is shift up a units.
f(x) - a is shift down a units.

Since function g is f(x + 4) then function g is the graph of function f(x) that shifts to left 4 units.
