F(x)=4x+2x^3-5,x=3 solve using direct substitution

61

Step-by-step explanation:

1) you know the values of x the make f (x)=3

it will be substituted in all variables

for this case we have the following expression:

to solve, we rewrite the expression as:

we apply double c and we have:

thus, the quotient is 48.

so, patel found a wrong ratio and the multiplication was incorrect.

option d

step-by-step explanation:

it will be a cylinder. with a diameter of 8 and 4 single pieces high
