Please help! functions operations. explain please

Answer:

a. 40

Step-by-step explanation:

Given

$g(x)=2x$ and $h(x)=x^2+4$

$(h\circ g)(x)=h(g(x))$

$(h\circ g)(x)=h(2x)$

We plug in 2x into $h(x)=x^2+4$ .

$(h\circ g)(x)=(2x)^2+4$

$(h\circ g)(x)=4x^2+4$

We now substitute x=-3.

$(h\circ g)(-3)=4(-3)^2+4$

$(h\circ g)(-3)=36+4=40$

The correct choice is A.

Find the equation for the line of best fit using the two points that are close to the line of best fit (2,70) and (4.5, 90)

kari74 [83]

Given:

Two points that are close to the line of best fit are (2,70) and (4.5, 90).

To find:

Th equation of best fit line using the given two points.

Solution:

We know that, if a line passes through the two points, then the equation of line is

$y-y_1=\dfrac{y_2-y_1}{x_2-x_1}(x-x_1)$

Two points (2,70) and (4.5, 90) are close to the best fit line.

Consider the two points (2,70) and (4.5, 90). So, the equation of line is

$y-70=\dfrac{90-70}{4.5-2}(x-2)$

$y-70=\dfrac{20}{2.5}(x-2)$

$y-70=8(x-2)$

$y-70=8x-16$

Adding 70 on both sides, we get

$y=8x-16+70$

$y=8x+54$

Therefore, the equation of best fit line is $y=8x+54$ .
