Exercise 50 Page 82

Substitute 12 for x to calculate the function's value.

456

Practice makes perfect

Using the function h(x), we want to evaluate for the given value, h( 12). To do this, we need to substitute 12 for x in each instance of the x-variable.

h(x)=4x^2-10x

Substitute

x= 12

h( 12)=4( 12)^2-10( 12)

CalcPow

Calculate power

h(12)=4(144)-10(12)

Multiply

h(12)=576-120
