Find an exponential function of the form y = ab* that passes through the points (0,4)
IrinaK [193]

Answer:

2nd option

Step-by-step explanation:

given an exponential function in the form y = ab^{x}

to find a and b use the coordinate points it passes through

using (0, 4 ) , then

4 = ab^{0} [ b^{0} = 1 ] , that is

a = 4 , so

y = 4b^{x}

using (2, 100 )

100 = 4b² ( divide both sides by 4 )

25 = b² ( take the square root of both sides )

\sqrt{25} = b , that is

b = 5

then exponential function is

y = 4 . 5^{x}

11. Let f(x) = 2x² + 7x + 5
Lady_Fox [76]

Answer:

(x+1)(2x+5)

Step-by-step explanation:

f(x) = 2x² + 7x + 5

Factor the expression by grouping. First, the expression needs to be rewritten as 2x²+ax+bx+5. To find a and b, set up a system to be solved.

a+b=7

ab=2×5=10

Since ab is positive, a and b have the same sign. Since a+b is positive, a and b are both positive. List all such integer pairs that give product 10.

1,10

2,5

Calculate the sum for each pair.

1+10=11

2+5=7

The solution is the pair that gives sum 7.

a=2

b=5

2x²+7x+5 as (2x²+2x)+(5x+5).

(2x²+2x)+(5x+5)

Factor out 2x in the first and 5 in the second group.

2x(x+1)+5(x+1)

Factor out common term x+1 by using distributive property.

(x+1)(2x+5)
