(30 points worth, pls help) Use the function f(x) to answer the questions. f(x) = −16x2 + 60x + 16 Part A: What are the x-intercepts of the graph of f(x)? Show your work. (2 points)

Step-by-step explanation:

x intercept y=0

0 = 16x^2 - 60x -16

0 = 16x^2 + 4x - 64x - 16

0 = 4x (4x + 1) - 16 (4x + 1)

0 = (4x - 16) (4x + 1)

4x - 16 = 0 or 4x +1 = 0

4x = 16 or 4x = -1

x = 4 or x = -1/4

(4,0) and ( -1/4,0)

x intercept y=0

0

= 16x^2 - 60x -16

0 = 16x^2 + 4x - 64x - 16

0 = 4x (4x + 1) - 16 (4x + 1)

0 = (4x - 16) (4x + 1)

4x - 16 = 0 or 4x +1 = 0

4x = 16 or 4x = -1

x = 4 or x = -1/4

(4,0) and ( -1/4,0)

Step-by-step explanation:

0  = 16x^2 - 60x -16

0 = 16x^2 + 4x - 64x - 16

0 = 4x (4x + 1) - 16 (4x + 1)

0 = (4x - 16) (4x + 1)

4x - 16 = 0 or 4x +1 = 0

4x = 16 or 4x = -1

x = 4 or x = -1/4

(4,0) and ( -1/4,0)

the answer is here: : )

:

logv3(x+2)=1

rewrite in exponential form:

logb(x) = y is equal to b^y =x

b = 3, y = 1

now solve for x:

3^1 = x+2)

x = 3-2

x = 1

see the picture for the graph.
