I need help with this

Answer 1

The expression will be given as h(8) = -0.3(8-5)²+7.5 the value of the function h(8) will be 6.3 feet.

What is an expression?

Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

Given that:-

• The function is h(x) = -0.3( x - 8)² +7.5

Now from the question when the boy jumped from a certain height he lands 8 feet farther away this condition will be expressed in the expression as follows:-

h(x) = -0.3( x - 8)² +7.5

Put x = 8 feet as

h(8) = -0.3(8-5)²+7.5

h(8) = -0.3 ( 3 )² + 7.5

h(8) = -2.7 + 9

h( 8 ) =  6.3 feet

Therefore expression will be given as h(8) = -0.3(8-5)²+7.5 the value of the function h(8) will be 6.3 feet.
