Y=-3x+8
when x=-2:
y=-3(-2)+8
y=6+8
y=14
when x=0
y=-3(0)+8
y=0+8
y=8
when x=2
y=-3(2)+8
y=-6+8
y=2

If f(x) = 2x2 + 1, what is f(x) when x = 3? a.1 b.7 c.13 d.19
prohojiy [21]

<u>Answer:</u>

The value of f(x) = 2x^2 + 1 when x=3 is 19, hence the correct option is ‘d’.

<u>Solution:</u>

A two degree polynomial equation is given in the question.

The equation is:

F(x)=2 x^{2}+1

We need <em>to find the value of f(x) when the value of x is 3. </em>

To solve a question like this we have to substitute the given value of x in the given equation and then simplify it.

Now let's substitute the value of x in the given equation.

F(x)=2(3)^{2}+1

First we square the number 3 and then multiply it with 2 and then add 1.

This is done because of the BODMAS rule, in which multiplication is given higher preference as compared to addition.

On solving the equation we get,

F(x)=2×9+1

F(x)=18+1

F(x)=19.

Therefore the value of f(x) when x=3 is 19.

Hence the correct option is ‘d’.

Anika [276]

Answer:

560 cubes

Step-by-step explanation:

Volume of prism: lwh, 7*4*2.5, 70cm!

Volume of cubes: lwh, 0.5*0.5*0.5, 0.125cm!

70cm/0.125cm=560 cubes.
