The table of values of function g(x) and the function f(x) = 5x3 + 2x2 – 6x + 7 are illustrations of exponential functions and polynomial functions

<h3>2. The type of function g(x)</h3>

The values on the table can be represented as:

(x, g(x)) = (-3, 0.375) (-1, 0.75) (1, 1.5) (3, 3) (5, 6) (7,12) (9, 24)

The above values show that as the values of x increases by 2, the values of function g(x) doubles.

Only an exponential function has this property.

Hence, the table of values represents an (a) exponential function.

<h3>3. Example of a polynomial function</h3>

A polynomial function is represented as:

y = ax^n  + bx^n-2 + .......... + d

Using the above format, the function that is a polynomial function is (a) f(x) = 5x3 + 2x2 – 6x + 7

<h3>4. Key features in the functions</h3>

The functions are given as

f(x) = 2x2 + 7x + 6

g(x) = 2x + 5

Set x to 0 to calculate the y-intercept

f(0) = 2(0)2 + 7(0) + 6 = 6

g(x) = 2^0 + 5 = 6

Hence, both functions have the same (c) y-intercept

I need help please!
Vlad1618 [11]

Answer:

\Huge \boxed{y=3x+6}

Step-by-step explanation:

y = mx + b

m = slope

b = y-intercept

The slope can be found from two points.

\displaystyle m=\frac{y_2-y_1}{x_2-x_1}

The two points from the graph are (1, 9) and (2, 12).

Plugging in the values and evaluating.

\displaystyle m=\frac{12-9}{2-1}

\displaystyle m=\frac{3}{1}

m=3

The slope of the line is 3.

The y-intercept of the line is where the line cross the y-axis.

The line crosses the y-axis at (0, 6).

b=6

The slope-intercept form of the line is:

y=3x+6

Combine like terms to simplify -1(2/7b + 9) -8
Rus_ich [418]

Simplify 2/7b to 2b/7

-1 × (2b/7 + 9) - 8

Simplify 1 × (2b/7 + 9) to (2b/7 + 9)

-(2b/7 + 9) - 8

Simplify brackets

-2b/7 - 9 - 8

Collect like terms

-2b/7 + (-9 - 8)

Simplify

<u>-2b/7 - 17</u>
