Which function is represented by the graph below?

Ymorist [56]

Answer:

$f(x)=2^x$

Step-by-step explanation:

Exponential function:

$f(x)=a(b^x)+c$

Step 1. Find a, y-intercept

Step 2. Find b, slope

Step 3. Find c, horizontal asymptote

a = 1

m = (y₂ - y₁)/(x₂ - x₁)

m = (3 - 1)/(1 - 0) = 2/1

b = 2

c = 0

$f(x)=1(2^x)+0\\f(x)=2^x$

Answer:

$\huge\boxed{\sf 7 + 5\sqrt{3} }$

Step-by-step explanation:

$(\sqrt{3} +4)(1+\sqrt{3})\\\\= \sqrt{3}(1+\sqrt{3} )+4(1+\sqrt{3})\\\\= \sqrt{3} + (\sqrt{3} )^2 + 4 + 4\sqrt{3} \\\\= \sqrt{3} + 3+4+4\sqrt{3} \\\\= 7 + \sqrt{3} + 4\sqrt{3} \\\\Take \ \sqrt{3} \ common\\\\= 7 + \sqrt{3} (1+4)\\\\= 7 + \sqrt{3}(5)\\\\= 7 + 5\sqrt{3} \\\\\rule[225]{225}{2}$

Hope this helped!

7th grade math. answer ASAP. If you answer correctly i will give thx, 5 star, and brainliest

Vitek1552 [10]

Hello there! When it comes to scientific notation, a number greater than or equal to 1, but less than 10 is multiplied by a power of 10. For example: 3.45 * 10^6. 0.95 is less than 1, so the first one is not in scientific notation. All of the others fit, because the numbers are greater than 1, but less than 10, and are mutliplied by a power of 10. The answer is A.
