7 0

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 <u>a</u> units.
  • f(x - a) is shift to right <u>a</u> units.
  • f(x) + a is shift up <u>a</u> units.
  • f(x) - a is shift down <u>a</u> units.

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