Suppose that the functions g and h are defined as follows. g(x) = (x + 1)(x+3) h(x)=-5x-1 (a) Find (6). g h (b) Find all values that are NOT in the domain of h If there is more than one value, separate them with commas. (a) (6) = [ h امه (b) Value(s) that are NOT in the domain of g | h ". 8 08 08 0.0. X Ś

Q: 3) Find domain of the following functions x+4 a) f (x) = x²+2x-8

A: Given function is: fx=x+4x2+2x-8 We have to find the domain of f(x).

Q: What is the vertex of the following function? f(x) = x² + 4x +3 (-1,4) (-2,-1) (4,3) (-4, 3)

A: Solution : Given that f(x) = x^2 + 4x + 3 For vertex of the given function , f'(x) = 0

Q: The function f(x) is defined as f(x) = 2x + 5. What is the value of f(- 7/4)? a. -17 b. 3/2 c. 17/2…

A: given f(x)= 2x+5 f(-7/4)= 2(-7/4)+5 =-7/2+5 = -3.5+5= 1.5 = 3/2 f(-7/4)= 3/2
